我试图在此之后创建一个Flutter插件：https://flutter.io/developing-packages/#step-1-create-the-package

flutter create --template=plugin -i swift hello

flutter doctor
Doctor summary (to see all details, run flutter doctor -v):

[✓] iOS toolchain - develop for iOS devices (Xcode 10.1)
[✓] Android Studio (version 3.2)
    ✗ Flutter plugin not installed; this adds Flutter specific functionality.
    ✗ Dart plugin not installed; this adds Dart specific functionality.
[✓] VS Code (version 1.28.2)

更新：我已将插件Dart和Flutter添加到Android Studio（现在Flutter医生是所有选中标记），但仍然没有运行按钮 . 请注意，这是一个生成的插件 . 我能够创建一个新的Flutter项目，但为此我不知道如何运行示例应用程序？

我可以使用 flutter run 运行示例代码，但在Android Studio中打开项目不显示任何运行按钮？
