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
| Feature | Dart | Kotlin |
|---|---|---|
| Developed By | Developed by Google. | Developed by JetBrains. |
| Primary Use | Mainly used with Flutter for cross-platform apps. | Mainly used for Android, JVM, and multiplatform apps. |
| Platform | Supports mobile, web, desktop, and server applications. | Supports Android, JVM, iOS, web, desktop, and server applications. |
| Compilation | Supports JIT and AOT compilation. | Compiles to JVM bytecode, JavaScript, or native code depending on the target. |
| Java Interoperability | Does not provide direct Java interoperability like Kotlin. | Provides strong interoperability with Java on JVM and Android. |
| Asynchronous Programming | Uses Future, Stream, and async/await. | Uses coroutines and Flow for asynchronous programming. |
| Popular Ecosystem | Closely associated with the Flutter ecosystem. | Widely used in Android, JVM, and Kotlin Multiplatform ecosystems. |
