About Dart

Dart is a general-purpose programming language designed by Lars Bak and Kasper Lund and developed by Google. It is engineered to make it easy for developers to build applications for any platform (multi-platform).

Dart is an Object-Oriented Programming (OOP) language. It uses a C-style syntax that can be compiled into JavaScript.

Why Choose Dart?

1. UI Optimization: Dart is specifically designed for creating user interfaces. Its syntax is easy to learn and familiar to those who have used other programming languages.
2. Productive Development: Dart features Hot Reload, which allows you to refresh the application output instantly without restarting the debug process. This significantly saves development time.
3. Fast Across Platforms: Dart supports multiple platforms, including ARM and ARM 64 for mobile, desktop, backend, and JavaScript for the web.

Platforms Powered by Dart

With Dart, you can write everything from simple scripts to full-featured applications for mobile, web, command-line, and servers. Its compilation technology is highly flexible:

1. Dart Native (VM JIT and AOT)

Targeted at mobile, desktop, server, and more.

• Flutter: Google’s toolkit for building natively compiled multi-platform applications from a single codebase.
• Dart VM JIT: A Just-In-Time compiler for rapid development and runtime optimization.
• Dart AOT: Ahead-Of-Time compilation for production-ready apps on ARM/ARM64, ensuring smooth and fast performance.

2. Dart Web (JavaScript)

Allows Dart code to run on any modern browser by compiling it into JavaScript.

• Dart Dev Compiler (dartdevc): Optimized for fast development cycles, supporting tools like webdev for running and debugging.
• Dart JS Compiler (dart2js): Produces highly optimized JavaScript for production use.

Your First Dart Program

The syntax is similar to C++, C#, Java, and JavaScript. Here is a simple “Hello, World!” example:

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

Output:

Hello, World!
