【问题描述】：
我正在尝试在 Android 设备上使用颤振制作的应用程序，当我尝试在手机上运行该应用程序时，我收到以下错误 “在根项目 'android' 中找不到任务 'assembleStageDebug'。”
我的应用在 iOS 上运行良好，但在 android 上运行时，它会导致问题。颤振医生没有发现任何问题，似乎没有人和我有同样的问题。我首先面临“不支持的Android插件版本：4.0.1”的问题。我被告知通过运行 -> 编辑配置 -> 风味添加风味并将名称添加到风味并使用 flutter run --flavor "flavor_name" 运行应用程序，这导致了此错误。提前致谢！
错误信息

* What went wrong:
Task 'assembleStageDebug' not found in root project 'android'.
* Try:

我以前也遇到过同样的问题。我做了颤振升级，它解决了问题。
