@override
void removeAll(Iterable<Object?> elements) {
  // Stop listening to the element that will be replaced
  for (E element in elements as Iterable<E>) {
    if (_propagateNotification &&
        element != null &&
        element is ChangeNotifier) {
      element.removeListener(_propagate);
    }
  }

  _values.removeAll(elements);
  notifyListeners();
