@override
void removeAll(Iterable<Object?> elements) {
  assert(ChangesNotifierHelperMixin.debugAssertNotDisposed(this));
  List<T> removed = [];
  for (final element in elements) {
    if (_set.remove(element)) {
      removed.add(element as T);
    }
  }
  if (removed.isNotEmpty) {
    notifyListeners(SetChangeDetails<T>(const [], removed));
