SetSignalMixin

SetSignalMixin is a mixin for a Signal that adds reactive methods for Set.

Note

This mixin only works with signals that have a value type of Set<T>.

class MySignal extends Signal<Set<int>>
    with IterableSignalMixin<int, Set<int>>, SetSignalMixin<int, Set<int>> {
  MySignal(super.internalValue);
}

void main() {
  final signal = MySignal({1, 2, 3});

  effect(() {
    print(signal.length);
  });

  signal.add(4);
  signal.remove(1);

  print(signal.contains(2)); // true
}
