未调试运行后，Flutter 无法识别为内部或外部命令

编程问答 2022-04-30

问题描述

enter image description here

当我对代码进行一些更改后尝试运行应用程序时会出现此问题。我尝试使用 vscode 命令 Run Without Debugging 运行，但出现此问题。当我删除 sdk 文件夹并再次下载它时，它会起作用。但这不是正确的方法，因为我每次运行应用程序时都应该下载新的 SDK

（同样在不调试的情况下点击运行后，Flutter is not be recognized as internal or external command 将显示在终端中，我不知道为什么但它真的很奇怪，即使我添加了路径变量）

下面是vscode的日志输出。
