UI & Widgets (P1)
- State: Use
StatelessWidgetby default.StatefulWidgetonly for local state/controllers. - Composition: Extract UI into small, atomic
constwidgets. - Theming: Use
Theme.of(context). No hardcoded colors. - Layout: Use
Flex+Gap/SizedBox. - Specialized:
SelectionArea: For multi-widget text selection.InteractiveViewer: For zoom/pan.ListWheelScrollView: For pickers.IntrinsicWidth/Height: Avoid unless strictly required.
- Large Lists: Always use
ListView.builder.
class AppButton extends StatelessWidget {
final String label;
final VoidCallback onPressed;
const AppButton({super.key, required this.label, required this.onPressed});
@override
Widget build(BuildContext context) => ElevatedButton(onPressed: onPressed, child: Text(label));
}
