Dart: Running Code & Tools

Running Dart

Install the Dart SDK from dart.dev. Then:

dart run main.dart           # compile and run
dart compile exe main.dart   # compile to native binary
dart analyze                 # static analysis / linting
dart format                  # auto-format code

Flutter (Dart's main use case)

Flutter is a UI toolkit by Google that uses Dart. It compiles to native ARM code for mobile, web, and desktop from one codebase.

flutter create my_app        # scaffold a new Flutter project
flutter run                  # run on connected device or emulator
flutter build ios            # build iOS release
flutter build apk            # build Android release
flutter build web            # build for web
flutter test                 # run Flutter tests
