android - flutter工具无法访问文件

Question

我尝试运行 Flutter 项目但出现错误

Flutter failed to write to a file at
"C:\Users\Dell\flutter-development\projects\flutter_complete_guide\ios\Runner\GeneratedPluginRegistrant.h". The flutter
tool cannot access the file.
Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current
user.

版本:
flutter 1.22.4，
window 10
我试图用 cmd 和 android-studio 创建一个 Flutter 项目，但结果是一样的。
我也为所有(包括戴尔用户)的 flutter-sdk 目录、flutter 项目及其子目录授予了完全权限。
一旦尝试使用 从头开始​​构建项目 flutter 创建 myapp
得到下一个错误

PS C:\src1\project> flutter create myapp
Recreating project myapp...
  myapp\android\app\src\main\res\mipmap-mdpi\ic_launcher.png (created)
Failed to send crash report due to a network error: SocketException: OS Error: Access is denied.
, errno = 5, address = clients2.google.com, port = 63568
Oops; flutter has exited unexpectedly: "FileSystemException: Cannot copy file to 'C:\src1\project\myapp\android\app\src\main\res\mipmap-mdpi\ic_launcher.png', path =
'C:\src1\flutter\packages\flutter_tools\templates\app\android.tmpl\app\src\main\res\mipmap-mdpi\ic_launcher.png' (OS Error: Access is denied.
, errno = 5)".

确保您拥有 Flutter 安装文件夹的所有权。查看 this出去。

OS Error: Access is denied.
, errno = 5

Error 5: Access denied is a known issue on Windows 10. This errorprevents you from installing software on your computer and accessingor modifying certain files.

The reason for this issue is the non-availability of the permissions.Windows 10 will prevent you from installing if you don’t have theAdministrator privileges or if your account is not the administratoraccount.

Getting administrator privileges for your account on the computer solves this problem.
