Flutter Bloc - Widget 树不断生长

Question

当我从最终视图返回到我的 "initial view" 时，所有 3 个 BlocProviders 中的每个 State 都被保存。

我不明白我错过了什么，一开始运行一切正常。

但是，当我在 GameView 中返回 InitialView 时，重新设置所有内容并再次移动到 GameModeSelectionView，它被多次调用（状态以某种方式保存倾倒的??)(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

这个过程随着每次迭代而增长(1)

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

Answer 1

我使用 MaterialPageRoute onGenerateRoute 解决了这个问题（因为我需要动态路由）

我将按钮 onPressed 方法中的代码替换为喜欢：

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

像魅力一样工作，不再长树。
