问题：

flutter doctor

运行命令 flutter doctor 报错：

 Android toolchain - develop for Android devices (Android SDK version 30.0.2)     ✗ cmdline-tools component is missing       Run `path/to/sdkmanager --install "cmdline-tools;latest"`       See https://developer.android.com/studio/command-line for more details.     ✗ Android license status unknown.       Run `flutter doctor --android-licenses` to accept the SDK licenses.       See https://flutter.dev/docs/get-started/install/macos#android-setup for       more details.

一般这个命令操作我们用不到，但是就是看着这个错误提示不爽，所以给它解决掉。

解决：

可以到Android Studio中配置 SDK Tools ， 勾选 Android SDK Command-line Tools (latest)

下载完成后：

再执行 flutter doctor 命令：

[!] Android toolchain - develop for Android devices (Android SDK version 34.0.0)
    ! Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses

按照提示执行命令：

flutter doctor --android-licenses

一直输入 y

最后：

再执行 flutter doctor 命令，结果 • No issues found! 一切正常了：
