Steps to reproduce
Steps to reproduce the behavior:
- We don't have clear steps for reproduction as this is coming from firebase console, however, open the the app from the public git repo. You will need to connect your own firebase with that.
- Press
Throw ExceptionButton and put your iphone app in background. - Observe the behaviour.
Expected Behavior
No exception should be thrown.

Thanks for the report @SdxCoder
I looked at the sample project you shared and it seems to contain third party package implementation like get_it, but in order to confirm whether the exception is indeed occuring only using firebase_crashlytics plugin itself, we would need a minimal reproducible code sample without any third party package code. If you can confirm that the exception still occurs without any outside code implementation, we can then properly address it.
Also, you can try implementing a runZonedGuard like below and check if using it, you still get the same crash or not:
await runZonedGuarded(() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterError;
runApp(MyApp());
}, (error, stackTrace) {
FirebaseCrashlytics.instance.recordError(error, stackTrace);
});
Thanks @darshankawar for reaching out. I have updated the repo, removed third party integration https://github.com/SdxCoder/handshake_exception_demo
Can you kindly check into it again. Thanks

Did you get a chance to use above in your code to check if it catches the error or gives any meaningful log that'll be helpful ?
@darshankawar i did used the code and deployed the suggested fix to production app. If we get the same crash again going forward, i will share logs. Unfortunately we only have firebase crash logs and no clear reproducible steps for that.
Thanks for the update. I wasn't able to replicate the repo you shared after updating it with my local firebase_options and running on iphone 6s (OS 15.3). Revisiting your original description, since you are getting handshake error and timeout, do you know how long the app stays in background ? because depending on the duration, the connection may be losing resulting in timeout.
Hey @SdxCoder. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.
If you have more information that will help us get to the bottom of this, just add a comment!
Since there haven't been any recent updates here, I am going to close this issue.
@SdxCoder if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
Hello @darshankawar, we used the code shared by you and we observed crash logs for couple of weeks and we still have this crash coming. But this time error logs is this
