What do the contents of the APK zip file look like before and after adding the fabric.io dependency?

The assertion failure indicates that the Flutter engine can not find the assets representing the application's Dart code.

Look for files in the APK such as assets/flutter_assets/isolate_snapshot_data, assets/flutter_assets/kernel_blob.bin, assets/flutter_assets/platform.dill, and assets/flutter_assets/vm_snapshot_data.

Are these files still present in the right places after adding fabric.io?

I also had the exactly same problem, can confirm that removing the apply plugin from fabric solves the problem, but is there a way to keep using fabric? Is it a problem with the fabric plugin itself?
