Dart vs Kotlin

Last Updated : 21 Sep, 2026

Dart and Kotlin are modern programming languages used to build applications across different platforms. Dart is strongly associated with cross-platform development using Flutter, while Kotlin is widely used for Android, backend, and multiplatform development.

  • Dart is developed by Google and is the primary language used with Flutter.
  • Kotlin is developed by JetBrains and is officially supported for Android development.

Dart

Dart is an object-oriented, class-based programming language developed by Google. It is designed for building fast applications and is commonly used with Flutter for developing mobile, web, and desktop applications.

  • Dart supports features such as object-oriented programming, async/await, null safety, generics, and type inference.
  • It can compile using both JIT (Just-in-Time) during development and AOT (Ahead-of-Time) for optimized native applications.

Example: Hello World Program

void main() {
print('Hello, World!');
}

Output:

Hello, World!

Kotlin

Kotlin is a statically typed programming language developed by JetBrains. It runs on the JVM and is widely used for Android development, server-side applications, and cross-platform development through Kotlin Multiplatform.

  • Kotlin is fully interoperable with Java, allowing developers to use existing Java libraries and frameworks.
  • It provides modern features such as null safety, extension functions, coroutines, type inference, and data classes.

Example: Hello World Program

fun main() {
println("Hello, World!")
}

Output:

Hello, World!

Dart Vs Kotlin

FeatureDartKotlin
Developed ByDeveloped by Google.Developed by JetBrains.
Primary UseMainly used with Flutter for cross-platform apps.Mainly used for Android, JVM, and multiplatform apps.
PlatformSupports mobile, web, desktop, and server applications.Supports Android, JVM, iOS, web, desktop, and server applications.
CompilationSupports JIT and AOT compilation.Compiles to JVM bytecode, JavaScript, or native code depending on the target.
Java InteroperabilityDoes not provide direct Java interoperability like Kotlin.Provides strong interoperability with Java on JVM and Android.
Asynchronous ProgrammingUses Future, Stream, and async/await.Uses coroutines and Flow for asynchronous programming.
