Can you tell about the Dart programming language and its main features?

Dart is a modern programming language developed by Google, often used for creating mobile, web, and server applications. Key features of Dart:

• Static typing with optional dynamic: allows writing safe and flexible code.
• Support for object-oriented programming: classes, inheritance, mixins.
• Asynchronous programming: built-in support for async/await for convenient handling of asynchronous operations.
• Compilation to native code and JavaScript: Dart can be compiled into native code for mobile apps (via Flutter) and into JavaScript for the web.
• Integration with Flutter: Dart is the primary language for UI development with Flutter, enabling the creation of cross-platform applications with a single codebase.

Example of simple Dart code:

void main() async {
  print('Start');
  await Future.delayed(Duration(seconds: 1));
  print('After one second');
}
