Question

我对Flutter还是很陌生，我在新机器上设置了flutter，但是“热重载”在这台机器上不起作用，flutter doctor随附未发现问题！，我有一个基本的应用程序，该应用程序可以随风飘动，而我只是想更改文本。调试控制台注册了我的ctrl + s，但说在94毫秒内重新加载了478个库中的0个。

这是我的日志：

它不能与ctrl + s或“闪光灯”按钮一起使用

奇怪！当我使用flutter run然后r时我注意到的另一件事是无需调试即可运行，而不是无需调试即可开始

您需要创建一个根窗口小部件以使热重新加载工作变得一帆风顺。如果您没有根窗口小部件（或在热重装不起作用时），则可以使用热重装按钮。有关更多详细信息，请访问： https://flutter.dev/docs/development/tools/hot-reload#recent-ui-change-is-excluded

热重装无法在VS Code中流畅运行
