warning

🛠

Warns when a FloatingActionButton does not have a tooltip specified.

Adding tooltip is important if you want your users with screen readers to be able to understand what the action is supposed to do.

Example

❌ Bad:

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

  @override
  Widget build(BuildContext context) => Scaffold(
        // LINT
        floatingActionButton: FloatingActionButton(
          onPressed: () {},
        ),
      );
}

✅ Good:

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

  @override
  Widget build(BuildContext context) => Scaffold(
        floatingActionButton: FloatingActionButton(
          tooltip: 'some tooltip',
          onPressed: () {},
        ),
      );
}
