Can Flutter Be Used to Create a Banking App

July 5, 2022 Comments Off Roxana read

Stable system performance, scalability, and data protection are important considerations when creating a banking app. In contrast, major fintech companies often provide new features and upgrades monthly or even weekly while developing full-fledged software solutions in three to five months. Therefore, financial institutions of any size need to enhance their time-to-market to stay competitive.

Choosing the right technology stack to design a banking app that meets quality criteria is critical. Engineers may automate the development process while providing a flawless user experience (UX) and maintaining data security by deploying software solutions that fulfill project criteria.

Cross-platform technologies are extensively used to create applications in the banking and finance sector because they allow organizations to cut expenditures and feature delivery cycles dramatically. Flutter and other cutting-edge technologies have made it feasible to construct high-performance, native-like solutions. Flutter has already been used to build software products by several well-known companies, including Rosbank and Nubank.

This cross-platform technology is an excellent choice if you’re working on a banking app. The advantages of using the Flutter framework in finance software development are discussed in this post by Surf software specialists.

What is Flutter?

It is possible to create mobile, web, and embedded apps using the open-source Flutter UI software development kit (SDK). Flutter allows programmers to develop a single codebase for several operating platforms, including iOS, Android, Linux, and Windows. Flutter was released by Google in 2017 and has since gained support from a burgeoning community of developers.

Flutter comes with a wide range of pre-built components:

A flexible framework in the React style;
A slew of Material Design-compliant widgets for iOS devices;
The 2D rendering engine for mobile devices;
Dart DevTools for testing and debugging software products;
Unit and integration testing application programming interfaces (APIs);
APIs and third-party SDKs for system connectivity;
Tools for developing, testing, and compiling applications using the command line.
Headless test runner for Mac, Windows, and Linux.

Flutter is now being used extensively in the creation of financial applications. Many financial institutions, like Rosbank and Kasikornbank, have already included this cross-platform architecture in their projects.

PracticeBank, a kids’ bank app, Fillit, an electronic wallet, and IBANshare, an app for safely storing numerous IBANs, are just a few of the many businesses and efforts that fall into this category (a mobile banking solution for families who travel).

Why would you use Flutter to develop a banking app?

Shorter development time and lower expenses for banking apps

Banks strive to reduce time to market while maintaining the quality of their solutions to obtain a competitive advantage and attract clients. By adopting Flutter, software developers may build a single codebase that can run on several operating platforms, saving them the expense of hiring multiple teams to develop native apps. Quality assurance engineers find software faults and potential problems sooner because they can work more quickly.

Flutter helps to faster product delivery by providing a comprehensive SDK. Furthermore, a cross-platform framework has a Hot Reload capability that lets programmers see real-time changes to the front and back ends. As a result, businesses may save time while creating and compiling financial apps. It’s worth mentioning that this feature isn’t given by native technology.

Additionally, Flutter’s user interface is simpler to design than many other platforms. Several Material Design widgets are available in Flutter that software specialists may modify.

Application security

Cross-platform frameworks like Xamarin, Ionic, and React Native are often less secure than Flutter financial applications. The Dart programming language is used to write Flutter code, which is then compiled into machine-readable code.

Compilation generates a native library with a complex structure and various data types. Reverse engineering has become more difficult, making it more difficult for hackers to replicate the program.

Consistent performance

Customer satisfaction and retention rates are directly related to a company’s performance. Consumers are less likely to use a banking application again if the content load time is long and the product performs badly under large loads.

Regarding speed, Flutter is capable of 60 frames per second. There are rare circumstances when software engineers may achieve even 120 FPS speed. If you’re looking for a banking app that can service a big audience and respond quickly, Flutter is an excellent solution.

Data security

Maintaining information security and compliance with standards such as GDPR and PCI DSS is vital as long as financial software solutions often store substantial volumes of sensitive data (for example, client personal data, and financial data).

Using Face ID or Touch ID, Flutter allows software developers to secure programs and data they store by enabling biometric authentication. Flutter’s implementation of these features is identical to that of native software.

Data security may now be enforced thanks to Dart developers’ library implementations of all common data encryption techniques. The use of cross-platform Flutter technology in banking apps may thereby improve data security.

facilitated app maintenance

Developing a banking application takes time and work, but it’s essential to keep it up-to-date to meet customers’ expectations. A financial institution may increase its impact on the market by releasing new products and upgrades based on consumer input.

The upkeep of a banking app is much easier since programmers have to develop one codebase to cover all platforms. Maintenance expenditures are also decreased as a consequence.

Here are a few examples of banking applications built using Flutter, including Rosbank, Europe’s first cross-platform mobile banking platform.

Rosbank, Europe’s first Flutter-based banking app

Since its founding in 1993, Rosbank has been a universal bank and a part of the global financial organization Société Générale. A mobile app for business customers was available when Rosbank approached Surf. However, the product was built on top of the old technological stack. As a consequence, introducing updates and expanding functionality was next to impossible. Customers also had difficulties with performance that impacted their experience.

However, Rosbank intended to construct an app with additional features simultaneously. It was chosen to use cross-platform technology because of the short launch deadlines for the project. As a cross-platform framework, Flutter enables developers to build high-performance, streamlined solutions while saving time and money.

The app was the first of its kind in Europe and the second in the world to use Flutter. The financial and insurance app won the Tagline Award for Best App.

Nubank creates new functionalities using Flutter

Nubank, a neobank founded in 2013, provides digital credit cards, personal loans, life insurance, and investment goods. The business includes offices in Germany, Argentina, and Mexico, and its home base in Brazil. The company’s rapid expansion was due to its ability to provide financial services to 48 million customers.

Nubank could not provide new solutions and enhancements promptly under these conditions. In addition, coordination between the iOS and Android teams got more challenging. As a result, new features for one platform would be released ahead of time for the other. Thus, Nubank may shorten the time between new features being released and maintain a high-quality level. The Nubank chose to employ a cross-platform framework for this reason.

After a comprehensive investigation of the current technologies, flutter was chosen as a cross-platform technology by software developers (Kotlin, Flutter, and React Native). Nubank’s software testers now access a wider selection of tools, better documentation, and a more reliable API.

Nubank could reduce the time it took to introduce a new feature by three times, thanks to the help of Flutter. It also improved speed and maintained a consistent user interface on all platforms. Flutter is now the major mobile banking app development technology in the organization.

Conclusion

Flutter is an excellent technology for building a banking app that achieves speed and fault tolerance since it is a feature-rich SDK widely accepted by the community. Flutter makes it feasible to design the UI and maintain a consistent user experience across different operating systems. In the financial sector, software specialists may use Flutter to enforce data security and boost protection against reverse engineering.

Using Golang From Fintech and Retail to Entertainment Platforms – Eight Use Cases

June 30, 2022 Comments Off Roxana read

With the help of its predecessors, C, PHP, and Python, Golang was created to be a simple and generally used programming language. In the context of business, it’s said to be an ideal solution, yet the issue arises: “Does it work?”

We’ve compiled a list of Golang use cases from various industries.

Fintech applications of Golang

Monzo is powered by Go on the creation of microservices and tools.

A financial services marketplace and online bank platform founded in 2015 offers a variety of products and services. The bank has been able to gain the trust and admiration of millions of clients thanks to a steady stream of new services, quick access to funds, and excellent technical support.

Monzo has used microservices from the beginning, while other startups often begin with monolithic systems. In reality, Monzo employs more than 1600 microservices. The bank chose Go because its numerous tools, which are unmatched in the development process, are microservice-friendly, performant, and resource-effective. It helped maximize the efficiency of computer resources, reduce lag time, and implement the most effective development strategies.

Solarisbank’s various teams use Go

German financial services firm founded in 2016 has developed an API platform that allows financial institutions to sell their goods through APIs, such as identification, payments, or cards. Several bank teams, including the Data platform, the Core banking, and the Authentication teams, use Golang.

A few comments about what Solarisbank utilizes Go for: pipelines for infrastructure creation, the reversal of authorization/authentication systems, proxies, and protocol-level banking systems development.

Use cases for Golang in payment processing systems

PayPal’s development pace was boosted using Go.

This U.S.-based company administers a payment system that is widely accepted across the globe, making it easy for customers to make online purchases. We’ve all used PayPal at some point to purchase or receive funds from a seller.

As the firm expands, it must stay on top of everything, including its preferred technology. PayPal experimented with a new programming language since its platform is becoming more complex. For both the organization and its customers, speed and reliability are critical. Developer productivity is essential to prevent issues connected to these needs. Programming languages must be simple, quick, and secure simultaneously to be effective. C++, the previous language in use, was effective but also too complex, causing IT engineers’ productivity to decline.

Golang proved the best language for building, testing, and pipeline release in this particular use case. Engineers found a 10% decrease in CPU consumption once PayPal began using it. And after six months of experimenting with Go, the development process was streamlined: programmers no longer needed to spend their time “code fighting,” allowing them to complete jobs more quickly.

American Express streamlined its payment process and achieved excellent results.

American Express is one of the world’s most well-known payment card service providers. For billions of people, the corporation offers a wide range of financial goods and services, including high-availability payments. As the number of transactions per second rises, American Express regularly updates its architecture and operations to keep up with the demand for lightning-fast payments and incentives.

When it comes to programming languages, Golang was an excellent choice because of its simple code, high security, and wide range of new features. In addition to Java, Node.js, and C++, the organization has previously utilized Go. A few engineers floated an idea at the organization to try out Go, so they organized a showdown to see how it compared to the programming languages they had previously used. Go came in the second position in terms of performance, completing 140,000 requests per second, and its toolset and various capabilities looked to be well suited to the company’s objectives.

Go has helped American Express update its payment processing and incentive programs as a fast, scalable, and easy-to-use microservices programming language.

Platforms for streaming audio and video content powered by Golang

Twitch’s favored method is Go for the heavy-duty systems.

Twitch is a video streaming network based in the United States that is mostly used for live-streaming video games and other entertainment material. Every day, the platform deals with the demands of approximately 30,000 users. Twitch hosts over 2 million concurrent video streams and sends over 10 billion messages daily via its chat feature. In addition, the corporation uses web APIs that process around 50,000 queries each second.

Too many individuals rely on Twitch due to its high availability and dependability to switch to another platform because of the lack of unexpected problems with Twitch. Twitch has selected Golang for an astonishing portion of its heavily loaded systems to achieve such astounding results:

C++ and Go are used to implement the transcoding system.
Most EDGE and distribution code is written in Go, ensuring the finest possible video quality.
Chat is written in Go to allow for scalability across several nodes.

With Go’s scalability, simplicity, and strong concurrency, Twitch’s programming language became unsurpassed because of its benefits. In addition, the company’s programmers constructed their own RPC (Remote Procedure Call) framework, allowing Golang backend services to connect effectively.

When it comes to developing specialized YouTube-like video streaming platforms, Surf has its unique tale. This package contains web and mobile applications for a company specializing in high-quality digital products.

Backend At 50 thousand requests per second, the platform was able to earn itself the title of #1 Entertainment App in the App Store because of the platform’s robust admin panel, analytics service, and appealing design.

SoundCloud accelerated its development process tremendously.

When it was first launched in 2007, this website-based online audio distribution network quickly grew to be one of the most well-known and biggest in the world, with users in 190 countries. More than three times the number of songs and 76 million monthly active users set the record for such services.

With Go, SoundCloud has selected an easy-to-learn, powerful programming language that can be used to build, deploy, test rapidly, and roll out new applications. Unit testing and near-real-time static analysis are also performed in Go because of their statically typed and compiled nature.

SoundCloud programmers say that using Go can focus on solving problems rather than on the language itself. They don’t have to spend additional time deciding on a method of code writing since there is typically just one technique to do the task. Even developers who are skeptical of Golang and unwilling to devote much time to learning it may rapidly begin generating simple, understandable code that enables for rapid execution of complex algorithms and procedures. As a result of this, they tend to change their minds. Furthermore, compared to the other languages SoundCloud employs, Go commits from zero to productive are the quickest.

In addition, Soundcloud relies on a number of Golang-based services and repositories. And as a result, the company’s backend developers are rapidly turning to Go for new projects.

Retail applications of Golang

Faster caching service for Allegro

Allegro is one of Europe’s most well-known e-commerce enterprises. More than 135 thousand sellers use it to attract 22 million monthly online consumers and provide them with a wide range of merchandise. Millions of people use the marketplace, and it keeps a lot of information.

Allegro designed a quick cash service with concurrent access to process multiple entries and removed them after a certain time to maintain the system’s dependability under heavy loads. Before Go, the organization utilized Python, Java, and PHP, which were more sophisticated and slower. Using a simple language with fast compilation and efficient memory management, the firm found its needed answer. The longest request that took 2.5 seconds was reduced to 250 ms thanks to the Go language’s FreeCashe function.

MercadoLibre upgraded its software and lowered its resource use.

Mercadolibre is an eCommerce firm that operates auction and online retail platforms. Today, it is one of Latin America’s major organizations in its field, with its headquarters in Buenos Aires.

The number of customers and transactions is continually increasing, new features are always being developed—and the company’s scalability requirements are demanding. Scaling was a real challenge with the old API architecture and stack. In order to take advantage of Go’s simplicity, scalability, and up-to-date tools, Mercadolibre gave it a go. Using this programming language, the organization could upgrade its software and obtain outstanding results in scalability.

For the company’s upcoming demands, Go helped them achieve greater performance, allowing them to handle 10 million requests a minute instead of the current 10 ms. Additionally, they now require 8 times fewer servers, have a 2x reduction in CPU utilization, and save an incredible amount of resources.

Conclusion

Fintech, retail, video streaming, and banking are just some industries that use Golang. Go is a popular choice in the financial sector because of its speed, availability, and ability to develop microservices.

Modernizing payments and incentives, enhancing performance, and improving development efficiency are all possible using Go in the payment processing industry. Cache services creation and request time reduction are some of Golang’s retail applications.

Go is a fantastic match for music and streaming platform development because of its high-loading nature and the speed with which commits may go from zero to productive.

To determine whether Go is a good match for your company, keep in mind that, despite the advantages, development costs aren’t that low. So, this language is best suited for large-scale projects, but if you don’t intend on expanding them, it’s not the ideal option for smaller projects. Using Go for small middleware development or building a POC for investors is a waste of time.

Why Big Tech is Turning to Rust

June 29, 2022 Comments Off Roxana read

The choice of programming language can make or break a project. If the developer fails to choose the right language, unforeseen obstacles might result in failure. Choosing the wrong programming language continues to cost developers and companies time and money.

Rust is a programming language that is often underrated and under-utilized because of its young age. On the contrary, Rust has a number of beneficial applications that many large tech companies are taking advantage of.

Read on to see why Rust is a language worth learning

What is Rust?

Initially established by a Mozzila developer, Rust can be described as a multi-paradigm, general-purpose programming language. With a similar syntax structure to C++, some developers struggle to adapt to the learning curve of Rust without a strong coding background in C or C++. Critics of Rust also point out the low number of open-source projects initiated by the company.

Regardless, Rust is lauded as providing superior memory protection and high performance to developers. It is becoming widely used in the IT sector and has seen a surge in popularity.

How can Rust boost your project?

Rust’s benefits

Rust is capable of executing both high-level and low-level tasks. This flexibility makes Rust perfect for multi-level programming and allows developers to perform hardware tasks easily.

Data Integrity

Arguably Rust’s strongest priority is data protection. If memory integrity threatens the success of the project, using Rust will minimize the risk. Users will be able to operate in safe mode, where memory is protected and software is unaffected by bugs or vulnerabilities during development.

Performance

Rust is a high-performance language that doesn’t sacrifice speed for data integrity. It has no runtime and no automatic memory space optimization. If necessary, it can access memory directly, greatly increasing program performance.

Developers can operate in unsafe mode if they find that safe mode is too inflexible. In unsafe mode, a developer’s code has the potential to cause bugs and even hardware failure, so it should be used with caution.

Concurrency

Concurrent errors are problems that arise at the same time between programs. Rust solves many of these concurrent errors as they are identified during compiling, making programs easier to develop. Rust also eliminates data races, which are elusive and damaging concurrency errors. Rust’s ownership feature only permits a single mutable reference to a data file at any one time. Thus, programs compiled with Rust don’t race each other for data.

Rust is cross-platform

Windows, Linux, and macOS all provide Rust support, greatly increasing the interoperability of developers throughout the tech sector.

For information on the Rust language’s multiplatform support, read their published information at https://doc.rust-lang.org/nightly/rustc/platform-support.html

Companies using Rust

The following examples underscore the highly-varied application of the Rust programming language in professional development environments

Mozilla

The company whose employee created Rust has used it to develop software, including the CSS engine used in the Mozilla Firefox browser.

Android

A mobile operating system purposed towards touchscreen and mobile devices, Android is working to bring Rust functionality to its open-source project.

AWS (Amazon Web Services)

Amazon uses AWS to provide cloud and API support to its customers. The company has used rust to develop APIs that provide simple storage, cloud computing, and much more.

Iqlusion

Iqlusion uses Rust to build software that provides the technical infrastructure to cryptocurrency systems and crypto-key security.

Should you use Rust?

Choose Rust if you prioritize control, performance, and memory integrity. Rust is frequently used for:

Embedded systems, OS, and microcontrollers: Many systems restrict the execution of languages from altering firmware of hardware-designated values. Rust has total control over hardware and memory, eliminating level restrictions on low-level applications.
Kernel driver development: Linux uses Rust as its second-official programming language due to its superior memory integrity features.
Replacement software parts: A foreign-function interface allows Rust to act as a secondary development environment for applications written using C without rewriting the program.

Although underrated, Rust has the potential to benefit you and your projects by providing you a fast, protected, and multi-leveled development environment. Rust has evolved solutions to the traditional concerns affecting C and C++. The increasing adoption of Rust by large IT companies can be considered an indication of its merits and should motivate any potential developer to learn the language in preparation.

Backend Engineer vs. Backend Developer: What are the Differences?

June 28, 2022 Comments Off Roxana read

Software teams often include jobs that are intertwined, making it easier to make mistakes in assigning responsibilities. Backend engineers and backend developers are often mistaken for one another. Ultimately, they’re all working together on the same software project. They may even perform comparable duties, particularly in Agile software development teams where members take on cross-functional responsibility to accomplish their objectives.

It’s important to note that a backend engineer and a backend developer are different. Despite their commonalities, they each have unique duties and talents that define what they bring to the table when producing software. We’ll look at each role’s qualities and the distinction between backend developers and engineers in this post.

Backend Programming Languages

Backend development uses two kinds of programming languages:

1. Object-oriented programming (OOP)

This programming paradigm is founded on the notion of classes and objects, which may hold both data and code. Data in the form of fields and operations in the form of functions.

In other words, it’s designed to make it easier to generate new instances of objects by breaking down the structure of a program into smaller, more manageable chunks of code (called classes).

Computer programs are written in OOP employ objects that communicate with one another, allowing the data inside them to be modified as desired by the user.

Many backend programming languages use object-oriented syntax, including:

C++

Python
.NET
Java

2. Functional

Functional programming is a programming paradigm in which programs are built by combining and applying functions.

Rather than a series of imperative statements, functions are defined as trees of expressions that map one value to another. It is possible to give arguments and return other functions from functions that have been tied to names.

The following functional languages are among the most popular:

Haskell
Clojure
Racket
Wolfram

The following are the most often used backend programming languages within these two paradigms:

PHP (Hypertext Preprocessor)

Web development relies heavily on PHP, a computer language known as the “Hypertext Preprocessor.” User data is often collected and stored in a database using this server-side programming language.

2. Python

Due to its interoperability with cutting-edge technologies like Machine Learning and the Internet of Things, Python has recently seen a surge in its user base. Many standard libraries make the job of programmers simpler in Python than in other programming languages. Additional improvements include enhanced code readability, compatibility with other languages, and GUI programming tools for developers.

3. Java

The backend web development industry relies heavily on Java. Enterprise-level web apps, Android, desktop, and scientific applications are common uses for this programming language. Cross-stage capability and security are two of Java’s strongest suits. Developers may link to databases, handle images, and more.

4. Ruby

Ruby is a dynamic and open-source programming language that emphasizes efficiency and ease of use. It can allow developers to construct web applications without having to write a lot of code. They can automate tedious activities, create online and mobile apps, and produce working prototypes. In addition, Ruby runs on almost all major operating systems, including Windows, Mac OS X, and Linux.

5. C#

This programming language has been listed in the top five for several years. Windows application development, game development, and more are examples of how it is utilized. The faster compilation, interoperability, component-oriented and structured language, and a slew of additional advantages come standard with the language. It also contains a wide range of libraries to aid programmers in their work.

Backend Development Requires a Certain Set of Skills and Tools.

Most backend professionals (engineers and developers) need a formal education to learn the fundamentals of their jobs. In many cases, they have graduate degrees in computer science or mathematics, as well as courses that are relevant to their work.

Depending on the work requirements, backend development requires a variety of talents. In addition to the languages above, a backend specialist should have the following abilities as well:

In-depth knowledge of how to deploy or host.
Familiarity with the concept of revision control (Git and GitHub).
Acquaintance with accessibility and security regulations in detail
Host environment and database management skills are required.
Understanding how to scale apps to deal with fluctuations in data flow volume.
Front-end technology knowledge is required (HTML, CSS, and JavaScript)
Knowledge of algorithms and data structures at a deep level.

Differences between a Back-end Engineer and a Backend Developer

There is a debate over the difference between a backend engineer and a backend developer since they both have comparable work and responsibilities. It’s important to note, however, that a backend engineer’s primary responsibility is to communicate with the company’s top executives to ascertain the end user’s needs. This gives them a clearer picture of how the application’s development should go and what it should look like at the end of the process.

On the other hand, a backend developer is mostly in charge of putting the ideas of a backend engineer into action. Software applications have been made feasible by combining single tasks and features.

Engineers are the ones who create the complete development system, not developers. They must show that the methodologies and designs they’ve developed for the project are workable, which is the responsibility of the backend engineers.

Backend Engineers and developers are in high demand. Go Remote

For a role like this, remote hiring is a huge advantage. Your talent pool will expand as a result of using remote recruiting. It is possible to recruit backend engineers or developers from any global country. Global recruiting not only allows you to save money on salaries but also to look for candidates in other parts of the world who have the knowledge you want.

Any firm searching for assistance with its software will almost certainly want the services of some backend engineer. Suppose you’re looking for a member of your development team who can handle critical responsibilities related to the creation and maintenance of your app. In that case, a backend developer may be the person for the job.

Despite their distinct characteristics, both jobs serve as a bridge between team members and customers.

Backend developers and engineers must be able to describe their methods to non-technical customers to demonstrate the site functionalities. They also give project reports, technical documentation, and textual communication on the project’s progress. Problem-solving, self-motivation, and effective time management are also essential for your applicant. Bottlenecks and problems might arise at any moment in a development project, as they do in all of them.

Remember that these soft skills are critical with remote teams as you begin your recruiting process. In addition to technical talents, you need someone who can work under pressure to develop innovative solutions for your app.

With the world at your fingertips, finding the appropriate candidate for your project is a cinch.

Best Performance Practices for Flutter

June 24, 2022 Comments Off Roxana read

Modern mobile apps must perform well to be successful. Having an app’s fragments skip and freeze makes users feel unwelcome and degrades its usability. A stuttering game is a completely unusable app, just like a slow e-commerce app. Discover how to improve your Flutter application’s performance with our article.

Other platforms like Flutter

This cross-platform framework uses the Dart programming language. Google’s Flutter is one of the most powerful solutions on the market. How does it compare to other mobile app technologies in terms of performance?

React Native

Flutter and React Native provide smooth scrolling at 60 frames per second. On the other hand, React Native consumes more battery power and memory, and the framework is less performant.

Flutter interacts with native components directly without requiring a ‘communication bridge’, and it includes a powerful rendering engine called Skia. This technology is fairly slow and can cause a bit of a performance hit.

Ionic

For opening web pages in apps, Ionic utilizes Web View, a system component. To develop the user interface, we use typical web technologies, like HTML and CSS. We just use the mobile app to create a browser, and it displays our UI. So Ionic apps are very different from those powered by Flutter or React Native. One of the biggest issues is low performance.

Xamarin

Flutter and Xamarin are two of the most popular frameworks for creating iOS and Android apps. It is important to find out which type of Xamarin framework is used – whether it shares code between platforms, or if it contains platform-specific code that applies only to each platform.

Measuring the performance of Flutter

Profile mode performance is measured with a real device (preferably a low-end one). Since Flutter provides a wide range of options for testing and measuring performance, performance testing can be done in several ways. Listed here are a few popular methods.

Performance widget (The Flutter Inspector, The command line)
Performance view (Flutter frames chart, Timeline events chart, CPU profiler)
Benchmark tests via integration testing

What you can do to improve Flutter performance

Don’t use expensive building methods, since they consume too much CPU power.
Utilize const Constructor to keep widgets in a constant state and avoid excessive widget rebuilding.
Opacity should only be used when necessary. If there is animation, the Opacity Widget will recompile every frame, which may cause Flutter performance issues.
When possible, avoid calling saveLayer since it is hardware-intensive.
16 milliseconds to build and render. Users won’t notice any significant difference in visual rendering if frames are rendered faster than 16ms, but it may improve battery life and reduce device heating.
Use The SizedBox widget. It is more efficient than the Container widget for defining a box or whitespace of specific dimensions.
Create child subtrees with AnimatedBuilder
Rather than ListView or Column, use the ListView.builder constructor if a list is not all present on a screen at once. A list’s elements are only saved in memory when they are displayed. It optimizes memory and increases performance.
In the case of a very large building method with hundreds of nesting levels, you may want to separate it into several methods. Even if some of the child widgets are completely static, this will force Flutter to rebuild them all every time the parent widget rebuilds. Split complicated widgets into smaller StalessWidgets to reduce CPU usage.

Conclusion

With Flutter, developers can build apps that offer native performance, even if they use visual effects heavily. We were surprised at how well Flutter handled animations and provided powerful playback controls. It is still highly recommended to follow best performance practices to avoid stuttering and errors in the application.

Creating an MVP in the World of Mobile Development

June 23, 2022 Comments Off Roxana read

Minimum Viable Product

How can you get the most bang for your buck when you invest in an idea? By developing a product that is at the bare least marketable. The MVP is a product that has just enough functionality for the initial consumers to use.

Your first prototype should be simple, with just a few features, so you can quickly get feedback on your concept. Why? Because it’s the fastest way to find out whether your app will be useful to your target audience and if it’s worth your time and money to continue developing it! If your premise about market demands is correct, then the MVP is like an experiment in the scientific process.

Designing and developing an app can be both times- and money-consuming, not to mention dangerous. You don’t want to waste your time and efforts on something that may not benefit your company.

The “need to have” features for your customers to install to achieve your project’s objectives may be determined by consulting your project stakeholders and defining the features they need. The costs and hazards associated with a project may be reduced significantly if an MVP’s scope is clearly defined as early as feasible.

So easy — instead of spending everything on something your clients may not initially desire, start small with an MVP and receive validation. Make it easy for your customers to express their needs and desires.

What is the best technology to utilize while developing an app?

Of course, when it comes to the Elixir programming language and Phoenix, we have to say: ELIXIR! It’s not as easy as that, is it? Everything hinges on the concept you’ve come up with and the development process you’ve chosen.

If you anticipate rapid expansion of your application and the associated processing of ever-increasing amounts of data, then Elixir is a logical choice. For an application with numerous users, sure, it’s possible. In order to grow your platform and include new tools and technologies, you should consider Elixir!

Your initial prototype, or MVP, will demonstrate the value of your idea and give you an idea of what further features your application will require. A thorough review of your MVP may define your future product and the resources you’ll need to produce it. Is it a good idea to start with a single technology for an MVP, then switch to a different one as your program grows? Of course not!

When developing an MVP software, many firms fail to consider expansion… Their primary objective is to swiftly and inexpensively produce a working prototype of their technology. However, if you want to save time and money in the long run, you may want to avoid rewriting your program in the future. There is usually no time to rework the product after the fact (and lack of money). A continuum is a good analogy for your early-stage project. Keep an eye out for procedures that may be necessary for the future. It will allow you to provide long-term company benefits.

There is always a lot of pressure to get things done quickly since other people work on comparable products at the MVP stage. The MVP’s cost is also a consideration. MVP places less emphasis on quality. On the other hand, Elixir is a great option if you’re looking for a fast, low-cost solution that doesn’t compromise on quality.

Elixir’s key benefit is that it’s fast and straightforward to create an MVP or a whole project. Let’s get into further depth and specificity about this idea.

Is Elixir a better choice than Ruby in terms of performance?

When it comes to developing an MVP application, Ruby has been the most popular choice. Ruby is one of the most widely used productivity languages; it’s no surprise. There is a direct correlation between the number of lines of code required to construct software and its productivity. Ruby, on the other hand, is just like that.

We in the Ruby community even have a saying: “There is a gem (lib) for that!”. If we wish to perform anything, there is usually an existing library that we can readily integrate into our code. Ruby is a highly productive language because of its simple syntax and many libraries. This implies that you may create an MVP project using Ruby for a reasonable price.

There’s no need to compare Ruby to Elixir when it seems like Ruby is the right option for MVP projects. Basically, scalability is the key. If your app is a success, you won’t need an MVP anymore; instead, you’ll have a fully working, scalable app. This is where Ruby falls short, and Elixir shines.

The general-purpose programming language Elixir was developed. It excels in a wide range of tasks. Elixir’s major benefits are its performance, efficiency, and scalability, particularly for web apps and IoT development projects. In addition, it is just as prolific as Ruby, making it a perfect choice for both MVP and scalability.

Despite its young age, the community around Elixir has been quite active in moving the technology forward. As a result, its standing compared to Ruby is becoming more comparable. In comparison to Ruby, Elixir is already well on its road to achieving a comparable level of functionality.

Additionally, José Valim, the guy that developed Elixir, is a major contributor to the projects Ecto, Phoenix, and a slew of other Elixir-related projects. He’s often mentioned in Elixir-related talks.

7 Ways React Native Can Reduce App Development Costs

June 15, 2022 Comments Off Roxana read

In today’s economy, businesses are always looking for new ways to save their money while also getting the most out of it. Unfortunately, if you’re a business looking at developing an application, this can end up being a costly endeavor if you are not familiar with what you are doing.

In this article, we will be going over how you can use React Native to reduce the cost of your Application development while also ensuring you get the most bang for your buck!

1. Reuse Components

Because of React Native’s ease of creating and reusing native components, creating cross-platform apps has never been simpler or smoother. By using React Native, you’re able to take elements from iOS and Android that would otherwise be used separately and leverage or reuse them with minimal flaws or glitches in the coding. According to Facebook, 85% of codes can be reused, meaning the less code you’d have to come up with, the less the app development is going to cost.

Rapid Development Time

With the amount of time it takes to develop an application, developers are always looking for new ways to reduce their development time. In our constantly growing technological times, this has never been easier than using React Native to code and develop your apps. Because React is simple and easy to use, development times are reduced, and therefore so is the cost of making the app. This frees up time to be better spent elsewhere, like marketing the app and preparing for its launch.

Better Team Management

In the past, creating cross-platform apps meant that your teams were expected to work with different programming languages and assets, making it harder to manage your team’s needs or relying on hiring more people to overlook a team based on expertise. By using React Native, your teams no longer need to struggle with coding as they use the same assets and elements for both iOS and Android. This can reduce your development costs as you no longer need additional employees in a team in order to have things running smoothly.

Less App Maintenance

Apps that are created with React Native are less likely to need ongoing maintenance. This is due to the fact that React Native is highly scalable, meaning it can be used on small-scale or large-scale apps that require a fast speed and loading time. Because of React’s minimalistic design and use, there is not much to maintain, and whatever coding is left can be fixed rather easily should anything be wrong.

Minimalistic UI Design

It doesn’t take a rocket scientist to know that the UI of a mobile app is the most important aspect of app development as this can make or break a user’s experience. Normally developing a cross-platform mobile app requires a good amount of time and money as you’d have to develop the mobile app for each platform separately. This is where React Native’s cross-platform compatibility comes in handy. Writing code for one can seamlessly be used for both platforms with little to no issue, cutting down the cost it takes by using other frameworks.

Fluid Integration

How apps run on their respective platform can have an impact on how the internal programming of the application is done. Some apps will work synonymously with each other and therefore need to be coded to allow these apps to work together. This is usually done when the GPS or Camera app needs to have access to your mobile application.

Easy Debugging

Another way to save costs is by how easy it is to debug or troubleshoot any problems that arise. Because of React Native’s user-friendly interface, it takes less time to problem solve an issue, and therefore costs are kept down.

These technologies are improving applications’ intelligence and intuitiveness, but they are also evolving with the increasing use of mobile app initiatives.

When it comes to user experience, AI and ML technologies play an increasingly important role nowadays. It’s a great example of how artificial intelligence (AI) has been incorporated into app development tools through automated mobile app UI testing tools. Several of these technologies, such as intelligent chatbots, recommendation algorithms, and easy search, bring value to app initiatives.

Most industries typically recognize artificial intelligence and machine learning across all niches as essential technologies for improving intelligence and optimizing their digital footprints for the target audience. However, keeping up with the fast improvements and trends in AI and ML technologies remains the toughest problem. A challenge and an opportunity await those willing to face these new technologies and their role in enhancing the user’s experience.

Virtual assistants and chatbots are a great way to see how AI and machine learning technology evolve. Intelligent technologies are now essential for any app to meet user expectations through in-app content offerings or features tailored to specific user contexts. They revolutionized how apps communicate with their users in real-time by providing them with relevant content and features.

As a result, today’s major app segment relies on the intuitive and intelligent capabilities these two technologies provide, from retail and mobile commerce to leisure and media streaming to mobile gaming and workplace applications. As a result of these two technologies, mobile apps have been at the forefront of this massive revolution.

Here are some examples of mobile apps where these two technologies have had the most significant impact on various aspects and contexts.

An easy-to-use mobile search engine

The growing popularity of voice search and voice interactions across applications demonstrates how artificial intelligence (AI) and machine learning (ML) technologies are being utilized to recognize voice commands and activate actions depending on user intent.

Encryption of User Identity.

Thanks to these new technologies, you don’t have to use transitory passwords and authentication data. The clever facial recognition technology can identify the real user regardless of your look or stride.

Apps for Smartphone Cameras

Smart camera applications have facilitated some of the most important advancements in AI and ML. Any item, face, food, natural phenomenon, or even water may be detected by an intelligent camera, and its settings can be adjusted appropriately for optimal output.

Artificial intelligence and machine learning have made it feasible to recognize faces in images and improve the picture with increased effects. Certain camera applications can identify food items and calculate the calories in a meal.

Intelligent Speaker Systems

With voice-controlled assistants like Amazon Alexa, we can now get things done quickly and easily. Several Internet of Things (IoT) smartphone applications might benefit from Alexa’s wide range of digital interfaces and smart home device compatibility.

These new speech interfaces allow consumers to connect with applications more naturally than ever before. Voice interfaces are becoming more intuitive and user-friendly than ever before because of Natural Language Processing (NLP) technology, a subset of AI technology. Context-driven computing is now possible with Google Home, thanks to Alexa’s innovations.

Smart speakers and voice interfaces are driving artificial intelligence (AI) into mobile apps gradually but steadily. Using simple voice commands, both Alexa and Google Home can get mobile app data and run applications simultaneously.

Transparency in Language Translation

AI and machine learning-powered translation applications may be a lifesaver for those who find themselves in situations where they need assistance communicating in a foreign language.

Artificial intelligence and machine learning (AI/ML)-based translation applications do not require an internet connection to conduct translations.

Emotional Recognition

New AI technology may do wonders for mobile app projects by recognizing emotions from inputs and facial expressions collected by the camera. Artificial Intelligence (AI) and machine learning (ML) have made it possible for applications to learn about the emotional state of their users in order to give relevant information and facilitate interactions.

When it comes to mobile app development, this might significantly impact the business. AI-powered applications may now use images and recorded voice intonations to distinguish between various moods and emotions. AI-powered analytics engine based on user history and other data-driven inputs can quickly determine the emotional state of mind of users, making it even more useful. Users will benefit from this in terms of content and interactivity.

Conclusion

For the first time, artificial intelligence and machine learning (AI/ML) technologies have invaded mobile applications that have never previously been seen. The app experience will continue to improve and grow due to these two technologies.
