颤振热重装不起作用。需要帮助

Question

Flutter热重载不适用于intelliJ / Android Studio。

一旦我在运行Android Q并已扎根的Poco F1上运行该应用程序，该应用程序就会在设备上运行，但是我无法重新运行该应用程序或对其进行热加载，则必须停止并重新构建。

我能够从应用程序中获取日志，因此没有连接问题。

我尝试过的事情：

1. 扑打干净
2. 增加的记录器缓冲区大小
3. 尝试使用Android Q模拟器
4. 尝试使用Android P模拟器
5. 尝试使用Android P的设备
6. 更改频道

以下是我扑打的医生-v：

如果我执行Flutter，请运行：

因此，即使我关闭设备上的应用程序，main.dart也不会停止。

任何主意是什么原因导致此问题以及如何解决？

Answer 1

我之前也遇到过同样的问题。我遇到了较旧的flutter版本的问题。运行以下命令

flutter clean
flutter upgrade

现在尝试运行该应用程序并检查热重装。
