我正在尝试运行命令“ flutter build appbundle --verbose”以生成我的应用的Android版本，并且收到错误“ Gradle task bundleRelease failed with exit code 1”。
我还不了解有关gradle以及您对每个软件包的依赖的很多知识，我已经阅读了一些堆栈溢出的答案，还重构了bundle.properties文件，但没有成功。这是我的构建信息：
flutter build appbundle --verbose部分输出

你们都有解决这个问题的建议吗？
我也曾尝试迁移到AndroidX，但没有成功。

我今天也遇到了这个问题。我部署了两个应用，具有不同版本的gradle版本。尝试这个。在android/build.gradle中尝试使用com.android.tools.build:gradle:3.3.1，似乎gradle 3.5给Flutter成功构建Appbundle带来了麻烦。
但是，如果您阅读here，则实际上是在build/app/outputs/bundle/<build-type>中创建了该附件

这是一个小问题，运行“Flutter clean”，然后运行“Flutter build appbundle”或“Flutter build apk”。
应该可以解决问题
