R8 Shrinker Error When Building AAB in FlutterFlow

[24n1]

Current Behavior

I'm encountering an error while trying to deploy my app to the Google Play Store. When building the AAB, I'm getting the following error:

FAILURE: Build failed with an exception.
Execution failed for task ':app:minifyReleaseWithR8'
> Compilation failed to complete: androidx.media3.exoplayer.dash.manifest.DashManifestParser

The error seems to be related to R8 code optimization with the media3-exoplayer-dash library. The full error message suggests using the --no-shrink flag, but I'm not sure how to implement this in FlutterFlow's deployment process.

Here's the complete error log:

BUILD FAILED in 5m 5s
Running Gradle task 'bundleRelease'...

[!] The shrinker may have failed to optimize the Java bytecode.
To disable the shrinker, pass the --no-shrink flag to this command.

I'm using a custom widget that implements video playback functionality. Has anyone encountered this issue before? Any suggestions on how to resolve this in the FlutterFlow environment would be greatly appreciated.

Expected Behavior

Shoud be deployed to Playstore without any issues as it had been until 2 days ago.

Steps to Reproduce

1. Created a custom widget using video_player package for HLS video streaming
2. Implemented the custom widget in my FlutterFlow project
3. Added video_player: ^2.8.7 to pubspec.yaml dependencies
4. Attempted to create an AAB for Google Play Store deployment through FlutterFlow
5. Build fails during the R8 optimization step with the ExoPlayer error mentioned above

Environment:

• FlutterFlow project
• Using custom widget with video_player package
• Building for Android release (AAB)

The error occurs consistently during the build process, specifically at the R8 optimization stage. I believe this is related to how the R8 shrinker is handling the ExoPlayer library that video_player depends on internally.

Reproducible from Blank
