跑步时flutter build appbundle我收到以下错误：
Gradle 构建无法生成 Android 捆绑包。
当在详细模式下运行时，这是我另外得到的：

我使用的是 Flutter 稳定频道 v1.2.1。
不过我可以毫无问题地构建 apk。
我还可以从另一个 Flutter 项目构建应用程序包。
根据上面的错误消息，您将如何开始查找问题？
这里可能有什么问题？
我有类似的问题和相同的错误消息。
（成功构建发布 APK，但构建应用程序包失败）
对我有用的解决方案是升级 Android Gradle 版本。
以下是适合我的配置（您也可以升级到最新版本）：
-
/android/gradle/wrapper/gradle-wrapper.properties:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip
-
/android/build.gradle:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
}
