颤振设置，android许可证未知，Windows，VS代码

Question

我有一个(看似常见的)未知的许可证状态问题。但是，常见的修复程序(如flutter doctor --android-licenses )没有起作用，这可以在下面的控制台输出中看到。我也去了链接--没什么用。

C:\Users\anonymous\OneDrive\Documents\Frameworks\flutter>flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
    X Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/windows#android-setup for more details.

! Doctor found issues in 1 category.

任何和所有的帮助都将不胜感激。预先表示感谢:)

安装Android命令行工具应该可以解决这个问题。导航到设置、外观和行为->系统设置-> Android

然后跑：

flutter doctor --android-licenses

它应该给你这样的东西：
