annotate_redeclares

Annotate redeclared members.

DO annotate redeclared members.

This practice improves code readability and helps protect against unintentionally redeclaring members or being surprised when a member ceases to redeclare (due for example to a rename refactoring).

BAD:

class C {
  void f() { }
}

extension type E(C c) implements C {
  void f() {
    ...
  }
}

GOOD:

import 'package:meta/meta.dart';

class C {
  void f() { }
}

extension type E(C c) implements C {
  @redeclare
  void f() {
    ...
  }
}

To enable the annotate_redeclares rule, add annotate_redeclares under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - annotate_redeclares

If you're instead using the YAML map syntax to configure linter rules, add annotate_redeclares: true under linter > rules:

linter:
  rules:
    annotate_redeclares: true
