Cross-platform app development is a massive trend for 2022. Companies need the flexibility and speed provided by cross-platform app development. This means developers need languages that can support this kind of heavy programming.

We’re comparing two popular languages to see which you should use for your next app in 2022.

What Is Dart?

Dart is a programming language that was released in 2011. It’s designed to create user-friendly interfaces, be user-oriented, and have above-average performance for various platforms and devices. Commonly used with Flutter, this Google-released language packs a punch.

What is Kotlin?

Kotlin runs on Java virtual machine (JVM), giving it access to Java’s library ring. Meant initially to substitute Java, this programming language proves it has an extensive range.

Technical Comparison

Why Use Dart Or Kotlin?

When you’re searching for the correct programming language to use, you’re looking for specific tools and features that will help you develop quickly and easily. Dart and Kotlin have a variety of Pros that make them excellent choices depending on your project.

Pros of Using Dart:

  • Google-backed
  • Works with Flutter
  • Great tools
  • Twice as fast as JavaScript
  • Scalable

Pros of Using Kotlin

  • Interoperability with Java
  • Functional programming support
  • Null safety
  • Code is clear and concise
  • Coroutines

Similarities and Differences

Dart and Kotlin are often mentioned in the same sentences because of their various similarities, including syntax, rules, and the kind of language they are. Both languages are Object-Oriented Programming Languages, making them similar in their actions and build

Dart and Kotlin are similar in their syntax. Dart is most often compared to its close cousin, C#, while Kotlin is like Java (unsurprising, considering it was meant to substitute Java)

Rules for writing comments and handling white spaces are similar between the two languages, making it easier to switch between one and the other. Their rules also make for easy integration of all the parts.


The most glaring difference between Kotlin and Dart is null safety. While Kotlin already supports this, it’s only in the BETA stage in Dart.

Cross-Platform Support

Dart has already established itself as a cross-platform titan thanks to its performance on Flutter.

Kotlin Multiplatform has emerged as an answer to this gaping disparity. While Flutter is praised for the Hot Reload feature that instantly shows the effect of changed code, Kotlin fires back with its code modularity and testability.

There’s no hard and fast answer about which is better when it comes to cross-platform support. Dart and Flutter are fantastic low-cost options that allow for one codebase. Kotlin works so seamlessly with Java that using it for any pre-existing Java work makes it an easy choice.

Commercial Comparison


Popularity among developers and customers can show which language might be the most user-friendly and help you gauge the ease with which you can hire a developer who is competent in your chosen language.

Dart Popularity According to Stack Overflow Developer Survey 2020-

  • 7th most loved language
  • 4% of respondents use Dart
  • 2% of questions every month are about Dart

Kotlin Popularity According to Stack Overflow Developer Survey 2020-

  • 4th most loved language
  • 8% of respondents use Kotlin
  • 1% of questions every month are about Kotlin

Learning Curve

The speed with which a team can become proficient with a language is critical, and Kotlin shows its strength here. There’s lots of documentation available for Kotlin, giving it a better learning curve than Dart.

App Development Costs

As both languages are open-source, this isn’t a cost concern. They both cut down on time and costs because of the speed they both offer through their single codebase.

Is Dart or Kotlin Better?

Every project is different, and a programming language might be great for one and awful for another. When Dart is used with Flutter, its popularity and flexibility are usually clear winners. Kotlin, however, is gaining speed of its own, making both languages heavy-hitters for cross-platform app development.
