warning

🛠

Pro+

Warns when a parent declaration is overridden by a declaration without an implementation.

Example

❌ Bad:

abstract class B {
  String get field;

  void foo();
}

abstract class A extends B {
  @override
  String get field; // LINT

  @override
  Future<void> foo(); // LINT
}

mixin M on B {
  @override
  String get field; // LINT
}

✅ Good:

abstract class B {
  String get field;

  void foo();
}

class C extends B {
  @override
  String get field => 'hi';

  @override
  Future<void> foo() async {}
}
