Warns when a getter provides access to an existing final field without any additional logic.

⚙️ Config

Set ignore-upcast (default is true) to ignore getters with the different return type than the referenced field.

Example

❌ Bad:

abstract class PageRoute<T> extends ModalRoute<T> {
  PageRoute();

  @override
  bool get barrierDismissible => _barrierDismissible; // LINT
  final _barrierDismissible = false;
}

✅ Good:

abstract class PageRoute<T> extends ModalRoute<T> {
  PageRoute();

  @override
  final barrierDismissible = false;

  String? _contents;
  String? get contents => _contents;
  set contents(String? value) {
    _contents = value;
  }
}
