I am developing an app using flutter on macOS. When i switch to windows machine for developing, it shows the following error
Oops; flutter has exited unexpectedly. Sending crash report to Google. Crash report sent (report ID: 4c15631f67927e73) Crash report written to D:\hcbmobile\flutter_11.log; please let us know at https://github.com/flutter/flutter/issues.
I have already created issue in this link: https://github.com/flutter/flutter/issues/33645

I have already tried flutter clean and flutter upgrade, but it did not work.
答案 0 :(得分：1)
我试图在 vs 代码终端中使用命令“flutter create”创建一个 flutter 项目，但我收到了这个错误
对我有用的是我关闭了 vsCode 并使用 powershell 而不是 vsCode 终端来创建项目，幸好它没有显示任何错误
答案 1 :(得分：0)
只需删除项目文件夹中的.flutter-plugins文件即可。
答案 2 :(得分：0)
我在使用 Android Studio 创建 flutter 项目时第一次遇到此错误。然后我也尝试 vs 代码和命令提示符。我遇到了同样的错误。
这些步骤帮助我修复错误；
1.删除现有的flutter文件夹。
2.转到此链接：flutter.dev/docs/get-started/install/
3.在新文件夹中再次安装flutter。 （仔细按照说明操作。）
不要将 Flutter 安装在像 C:\Program Files\ 这样需要提升权限的目录中。
4.再次设置环境变量。
5.run flutter doctor
（如果一切设置正确，就不会出现错误。）
6.在您的项目目录中创建一个项目。
完成:)
