Flutter 检测报错 Unable to locate Android SDK.

安装好 Flutter SDK 之后，官方建议使用flutter doctor检查 Flutter SDK 的相关配置信息。

如果 Android Studio 安装 Android SDK 的时候选择了自定义路径，Flutter 提示无法定位 Android SDK 的安装位置。以下为报错信息：

[X] Android toolchain - develop for Android devices
    X Unable to locate Android SDK.
      Install Android Studio from: https://developer.android.com/studio/index.html
      On first launch it will assist you in installing the Android SDK components.
      (or visit https://flutter.dev/docs/get-started/install/windows#android-setup for detailed instructions).
      If the Android SDK has been installed to a custom location, please use
      `flutter config --android-sdk` to update to that location.

提示给出了修复建议，使用flutter config --android-sdk [Android SDK 路径]命令设置 Android SDK 的自定义路径。设置时去掉多余的[]符号。

以下是设置成功后显示的信息：

PS C:\Users\shiramashiro> flutter config --android-sdk E:\DevKits\Android\Sdks
Setting "android-sdk" value to "E:\DevKits\Android\Sdks".

再次使用flutter doctor检查 Flutter SDK 的配置信息。
