英文:
Flutter App stuck on "app running gradle task 'assembledebug..."
问题
这是我的第一个Flutter应用程序，我尝试运行Flutter提供的示例，但它卡在这个消息上：running gradle task 'assembledebug....，或者过了一段时间后出现错误：Exception: Gradle task assembleDebug 失败，退出代码为1。
尝试了所有在类似问题中提到的方法。使用SDK版本30，Android Studio版本3.1和Flutter版本1.20.1。

在你的Android Studio中，进入android目录，然后从终端运行：
gradlew clean
gradlew build
然后运行该应用程序。
如果不起作用，请尝试运行flutter clean。
还要删除用户目录中的.gradle文件夹。
这会花费一些时间，但它将运行。
英文:
In your android studio, cd to android directory then run from terminal:
gradlew clean
gradlew build
and then run the application.
If it wont work try flutter clean.
Also delete the .gradle folder in Users directory.
it will take some time but it will run.
