Question

我正在尝试运行一个Flutter应用程序，但是由于某种原因，我无法弄清楚，它将无法运行。这就是我跑步时得到的。我确实在系统路径中添加了颤振/ bin程序，但是那也不起作用。重新格式化窗户后发生了这种情况。我所做的正是：

安装Android Studio
下载flutter sdk
在Android Studio中添加了flutter插件。

这是我在格式化PC之前第一次进行的操作。而且有效。

Launching lib\main.dart on Mi 9T in debug mode...

转到文件：E：\ codes \ flutter \ im_poor \ build \ app \ intermediates \ signing_config \ debug \ out

然后选择signing-config.json文件

然后通过shift + delete删除文件
