This is not the way Flutter widgets are supposed to be used.这不是应该使用 Flutter 小部件的方式。 Widgets (even StatefulWidgets) generally do not hold application state.小部件（甚至是 StatefulWidgets）通常不保存应用程序状态。 They should only provide a view on state managed elsewhere.他们应该只提供对别处管理的状态的看法。
There are many proven methods of application state management that are popular and well supported in Flutter.有许多经过验证的应用程序状态管理方法在 Flutter 中很流行并且得到了很好的支持。
