Dart 3.3+

Warns when an extension type exposes a member that renames an existing representation field member.

info

This rule is different from annotate_redeclares.

It only works for getters (for extension types with and without implements) and does not rely on the @redeclare annotation.

Example​

❌ Bad:

extension type ET(String _value) implements String {
  bool get isEmpty => _value.isNotEmpty; // LINT

  bool get isNotEmpty => this._value.isEmpty; // LINT
}

extension type ET2(String public) {
  bool get isEmpty => public.isNotEmpty; // LINT

  bool get isNotEmpty => public.isNotEmpty;
}

✅ Good:

extension type ET(String _value) implements String {
  @redeclare
  bool get isEmpty => _value.isEmpty;

  @redeclare
  bool get isNotEmpty => this._value.isNotEmpty;
}
