在我的环境中，Gradle版本似乎有问题。我一整天都无法创建发行版，而且似乎无法理解解决此问题的方法。
运行flutter build apk -v时，我有以下日志：https://pastebin.com/U825yH0H
这是flutter doctor -v的结果：

flutter analyze不会产生任何错误。
在另一条路径上，如果我尝试使用Android Studio的构建工具，则在尝试生成appbundle时发现自己将Android Gradle插件更新为3.2.0或更高版本的请求。我可能会误会，但似乎我已经在使用Gradle 5.1.1。
最后，以相同的过程生成一个发行版APK很快就会产生：
