annotate_overrides

Annotate overridden members.

This rule is available as of Dart 2.0.0.

Rule sets: recommended, flutter

This rule has a quick fix available.

Details

DO annotate overridden methods and fields.

This practice improves code readability and helps protect against unintentionally overriding superclass members.

BAD:

class Cat {
  int get lives => 9;
}

class Lucky extends Cat {
  final int lives = 14;
}

GOOD:

abstract class Dog {
  String get breed;
  void bark() {}
}

class Husky extends Dog {
  @override
  final String breed = 'Husky';
  @override
  void bark() {}
}
