Flutter 守护进程已终止

Question

在 VS Code 上启动 Flutter 应用时出错

我在互联网上尝试了很多解决方案，但都没有奏效，我也尝试重新安装 Windows，但也没有用

Answer 1

我已通过以下步骤解决了此错误：

1. 转到 {C://Users/{Name}/.gradle} - 删除 .gradle 文件。

2. 然后在其他位置下载并安装相同的flutter和dart SDK版本并设置环境变量。

Example:

Environment variables Before : ("D:\FlutterExtractedFiles\flutter\bin") ("D:\FlutterExtractedFiles\flutter\bin\cache\dart-sdk\bin")

Environment variables After : ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin") ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin\cache\dart-sdk\bin")

1. 然后请检查 android studio 事件日志
