感谢您对我的问题的回复。花了很长时间后，我找到了解决办法。

我遵循了以下步骤：

将grade.properties文件更新为：

distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip

将项目级build.gradle文件中的依赖项更新为：

classpath 'com.android.tools.build:gradle:4.0.1'

清洁并获得pug:

flutter clean
flutter pub get

现在构建您的项目。它成功地工作了。

我想我的问题与distributionUrl有关
