android-studio - 无法找到开发设备Flutter

Question

我有 flutter 打的问题。我安装了Android Studio并将其配置为使用flutter(安装flutter和Dart)，但无法在任何设备上运行我的应用，并且返回了android studio控制台:

Unable to locate a development device; please run 'flutter doctor' for information about installing additional components.

和 flutter 医生-v:

仅仅设置ANDROID_SDK_ROOT环境变量是不够的。为了使这个对我有用，我还必须做:

flutter config --android-sdk $ANDROID_SDK_ROOT

重新启动Android Studio后，它开始为我工作
