Flutter Bloc-小部件树不断生长

Question

当我从最终视图返回到“初始视图”时，所有3 State中的每个BlocProviders被保存。

请参阅小部件树：

我的代码在这里链接： GIST

我不知道自己缺少什么，在第一次运行时一切正常。

但是，当我回到InitialView时回到GameView时，请重新设置所有内容并再次移至GameModeSelectionView，它被多次调用（状态以某种方式保存而不是转储??）（1）：

flutter: State of GameSelectionState GameSelectionInitial
flutter: State of GameSelectionState GameSelectionStart
flutter: State of QuestionState StopQuestion
flutter: OK?
flutter: State of GameSelectionState GameSelectionStart
flutter: State of QuestionState StopQuestion
flutter: OK?
flutter: State of GameSelectionState GameSelectionStart
flutter: State of QuestionState StopQuestion
flutter: OK?
flutter: State of GameSelectionState GameSelectionInitial

此过程随着每次迭代（1）

我正在使用flutter_bloc依赖项： https://pub.dev/packages/flutter_bloc

Answer 1

我使用MaterialPageRoute onGenerateRoute解决了该问题（因为我需要动态路由）

我将Buttons onPressed方法中的代码替换为：

Navigator.of(context).pushReplacementNamed(
              GameModeSelectionView.routeName,
              arguments: players);

像魅力一样运转，不再生长一棵树。
