我不知道如何处理这个问题了。关于这个问题没有好的文件。
我尝试过将gradle升级到最新版本，以及升级构建工具等等。有些人甚至让我运行flutter doctor --android-licenses，我照做了，但没有成功。
错误：
FAILURE: Build failed with an exception.

附言：我已经安装了Flutter和Dart插件。不知道为什么它仍然被列为未安装。我已经重新启动电脑好几次了。我也不知道为什么它不能确定捆绑Java版本。
请检查您的android SDK。记下您的SDK路径(SDK_path(，然后将其用于配置。这是命令：
flutter config --android-studio-dir="SDK_path"
然后再次运行扑动医生。
