Dart is the primary language used with Flutter, a UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase. Dart syntax is similar to JavaScript, Java, and C#.
It supports both ahead-of-time (AOT) compilation for high performance and just-in-time (JIT) compilation for fast development cycles with features like hot reload.
Key Features of Dart
- Optimized for UI: Dart was designed to create smooth, high-performance user interfaces with features like async/await and isolates.
- Null Safety: Modern Dart includes sound null safety to eliminate null reference errors at compile time.
- Cross-Platform: Dart compiles to native ARM, x64, and JavaScript, making it suitable for mobile, web, and backend development.
- Rich Standard Library: Dart comes with a robust core library for collections, async programming, math, and more.
Example Code
void main() {
var name = 'World';
print('Hello, $name!');
}This basic Dart snippet prints 'Hello, World!' and demonstrates Dart's simple syntax.
