avoid-unnecessary-stateful-widgets

added in: 1.4.0

Warns when a StatefulWidget can be converted to a StatelessWidget.

Using a StatelessWidget where appropriate leads to more compact, concise, and readable code and is more idiomatic.

Example

❌ Bad:

// LINT
class MyWidget extends StatefulWidget {
  const MyWidget({super.key});

  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  @override
  Widget build(BuildContext context) {
    return Container();
  }
}

✅ Good:

class MyWidget extends StatelessWidget {
  const MyWidget({super.key});

  @override
  Widget build(BuildContext context) {
    return Container();
  }
}
