@override
int removeWhereEmit(bool Function(T item) test) {

  final originalLength = updated.length;
  updated.removeWhere(test);
  final removedCount = originalLength - updated.length;

  if (removedCount == 0) return 0;

  _onInsertionCallback?.call(updated);

  _refreshDataAge();
  emit(

      allItems: updated,
      items: updated,
      lastUpdate: DateTime.now(),
      fetchedAt: _lastFetchTime,
      dataExpiredAt: _getDataExpiredAt(),
