我有相同的错误消息类似的问题。（成功创建APK版本，但未能构建应用捆绑包）对我有效的解决方案是升级AndroidGradle版本。以下是适用于我的配置（您也可以升级到最新版本）：
：distributionUrl=https://services.gradle.org/distributions/gradle-4.10.2-all.zip
：buildscript {repositories { google() jcenter() }dependencies { classpath ’com.android.tools.build:gradle:3.2.1’}
}
解决方法运行 flutter build appbundle时，出现以下错误：Gradle构建无法生成Android捆绑包。
当以详细模式运行时，这是我另外得到的：

我在Flutter稳定频道v1.2.1上。
我可以毫无问题地构建apk。我还可以从另一个Flutter项目构建一个appbundle。
根据以上错误消息，您将如何开始查找问题？这可能是什么问题？
