Build Failed while trying to sign Bundle

Help/Discuss
1

No matter what I do, I can’t seem to get rid of this error. I’ve generated new keystores, made sure the keystore.properties file is in the right spot, verified all the information is consistent between that and my app\build.gradle. I’m using flutter through Android Studios but I can’t figure out what I’m doing wrong or missing.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:signReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.FinalizeBundleTask$BundleToolRunnable
   > java.lang.NullPointerException (no error message)

Do what the error suggests and run Gradle with --stacktrace or optimally --scan if possible. Then you should see where the NullPointerException is coming from.
