After migrating from Flutter SDK 3.16.9 to Flutter SDK 3.19.6, the Android release build gets stuck in the splash screen, these are the logs:

E/flutter (15679): 

Line 46 in bootstrap file is making use of kDebugMode constant for set the Crashlytics collection value, I've also tried removing it and providing true to it but it throws same errors.

await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true); // This also fails

If I remove Crashlytics from the project everything works as expected.

Reproducing the issue

Add Crashlytics to a project and run in release mode or make a build and open it in a physical device.

Hi @fbardecio - I tested on release mode, flutter v3.19.6 using Crashlytics example app, no crash for me. You'll need to create a small, reproducible code sample/repo to investigate. Thanks.

Hey @russellwheatley thanks for taking a look into this issue, I will try to reproduce this in a small project during this weekend and share access to it/any news with you!

[russellwheatley]

@fbardecio Thanks 🙏

[fbardecio]

I've created a new project with only the specified Firebase dependencies and I was not able to reproduce this issue, it is probably related to some other Android configuration located in my main project repository, I will keep investigating, thanks for taking your time to review it 🙌
