Introduction to Dart

Dart is a language built by Google for building fast apps on any platform — it's best known today as the language Flutter apps are written in. Its syntax will feel familiar if you've used Java, JavaScript, or C#.

Example: a minimal Dart program

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

Hello, world!

Every Dart program starts execution from a main() function — no wrapping class required, unlike Java or C#, which is one small but real difference even though Dart's overall style leans C-family. If you continue into the Flutter subject after this one, everything you learn here about variables, functions, and classes transfers directly, since Flutter code is Dart code.
