Crashed: com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS

[Tom3652]

Steps to Reproduce

Unfortunately i am unable to reproduce it for now and it happens only in release mode affecting my beta testers.

The error description is :

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x2d623636612d6365

This crash occurred 10 times and each time with a little bit different StackTrace apparently.
I have made this issue because of the FirebaseDatabase log in the trace, but there is no such logs in more recent errors.

I have also focused on firebase_database because it's the main change between my 0.0.06 release and 0.0.07 including a real time chat feature in app.
I have also added flutter_sound_lite to play and record audio messages.
According to the popularity, i would think now that the error would come from the flutter_sound_lite rather than firebase_database, but FirebaseDatabase appeared in the first logs sequences so...
There is no evident log for me pointing towards a specific package anyway, it could be conflict between several packages as well (flutter_sound_lite and camera for example...)

In addition, the latest crash gave these keys :

I will update the full trace (you will see the difference with the one in FlutterFire repo that i have mentioned.
Below you will see the latest crash (with the above keys).

Expected results:

The app should not crash.

Actual results:

The app is crashing.

@flutter-symbolizer-bot #95568 (comment) ios release arm64

[flutter-symbolizer-bot]

@darshankawar No crash reports found. I used the following overrides
when looking for reports

SymbolizationOverrides(engineHash: null, flutterVersion: null, arch: arm64, mode: release, force: false, format: null, os: ios)

Note that I can only find native Android and iOS crash reports automatically,
you need to explicitly point me to crash reports in other supported formats.

If the crash report is embedded into a log and prefixed with additional
information I might not be able to automatically strip those prefixes.
Currently I only support flutter run -v, adb logcat and device lab logs.

See my documentation for more details on how to do that.

@Tom3652
Does the stack trace shows something like CrashDoctor Diagnosis: or Application Stats at the end of the trace ?
If so, can you provide the same ?

[RomainFranceschini]

@darshankawar hi,
I'm facing a similar issue. Below is a sentry crash report with symbolication https://sentry.io/share/issue/715ae351e141453da7731bb01276b1f9/

[Tom3652]

@darshankawar no there is nothing like you show. However, when i check the other 9 crashes with the same error i am getting these differences :

On one of the crash / 10 i am getting the following as the second trace :

This is actually the trace i have provided here.

All of the remaining trace is the same except the number of Thread or DartWorkers that changes a bit.
