Extension: SetSignalExtension#

extension SetSignalExtension on Signal<Set<E>>

Helper extensions for [Signal<Set>] to perform mutation operations that automatically notify downstreams.

Under the hood, these methods mutate the underlying set and call set(..., force: true) to trigger all listeners and computations.

import 'package:signals_core/signals_core.dart';

final tags = <String>{}.$;

effect(() {
  print('Tags: ${tags.value}');
});

tags.add('dart'); // Automatically prints: Tags: {dart}
tags.addAll(['flutter', 'signals']); // Automatically prints: Tags: {dart, flutter, signals}
