On running
flutter build appbundle I am getting the following error:
Gradle build failed to produce an Android bundle package.
When running in verbose mode this is what I additionally get:

I am on Flutter stable channel v1.2.1.
I can build an apk without a problem though. I can also build an appbundle from another Flutter project.
Based on the error messages above how would you start to find the issue? What might be the problem here?

In some cases when your Gradle files are deleted or corrupted you will not be able to download new Gradle files in android studio. In this case, we have to delete the Gradle files which are present already and then again sync your project to download our Gradle files again.
This kind of issue usually appears either due to a gradle misconfig or in your case, it looks more of an internet issue. Try running flutter clean in your project source and then using flutter build appbundle and check whether you're able to run the command without any errors.
Open Gradle tab. Select path to Build. Gradle file. Double click to sync.
I have similar issue with the same error messages. (Build Release APK successfully but failed to build app bundle) The solution that works for me is to upgrade the Android Gradle Version. Below are the config that works for me (You may upgrade to the latest version also):
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'
}
}
