Warns when a class inherits Equatable but is missing the props getter.

Example

❌ Bad:

// LINT: This class inherits Equatable, but is missing the 'props' getter. Try adding it.
final class Child extends Parent {
  final int y;

  Child({required this.y});
}

sealed class Parent with EquatableMixin {
  @override
  List<Object?> get props => [];

  Parent();
}

✅ Good:

final class Child extends Parent {
  final int y;

  Child({required this.y});

   @override
  List<Object?> get props => [...super.props, y];
}

sealed class Parent with EquatableMixin {
  @override
  List<Object?> get props => [];

  Parent();
}
