Example

❌ Bad:

class MyWidget extends HookWidget {
  void myCallback() {
    useMemoized(() => null); // LINT
  }

  @override
  Widget build(BuildContext context) {
    return FloatingActionButton(onPressed: () {
      useMemoized(() {}); // LINT
    });
  }
}

✅ Good:

class MyWidget extends HookWidget {
  @override
  Widget build(BuildContext context) {
    useMemoized(() {});

    return FloatingActionButton(onPressed: () {
      ...
    });
  }

  void _useMyHook() {
    useMemoized(() => null);
  }
}
