    _incrementController
        .scan<int>((sum, _v, _i) => sum + 1, 0)
        .pipe(_countController);
  }

  ValueStream<int> get count => _countController;
  Sink<void> get increment => _incrementController.sink;

  @override
  void dispose() async {
    await _incrementController.close();
    await _countController.close();
  }
}
