[FIXED] Flutter Execution failed for task ':app:minifyReleaseWithR8'

Issue

I want to build an app bundle for my flutter project, however I get an exception every time. Here is the terminal message:

I assume the error is related to some kind of Java stuff because of the KeyFactorySpi$Ed25519.class but I can not end up with something meaningful.

Solution

I solved the issue. implementation 'com.facebook.android:facebook-android-sdk:latest.release' was causing this problem. I assume that it conflicts with the flutter_facebook_auth package added via pubspec.yaml file. I removed this dependency and now everything is just working fine.
