[crashlytics] Fatal errors not getting caught / reported.

Fatal errors not getting caught / reported.

I have crashlytics integrated and connected to firebase console.
I can see firebase.crashlytics().recordError(...) in the console. But firebase.crashlytics().crash() fails to record. Logcat says "No record found." on restarting the app.

The same setup works on iOS

BTW. the issue is only in dev mode. works in production.

This is because RN catches these in Dev so it can display the RedBox; I'm not sure there's anything that can be done about it afaik but I will look at it as part of v6.0.0, you can track this via: https://github.com/orgs/invertase/projects/2#card-17470855

Ok, makes sense. I would suggest adding a note about it in the docs. I spend good amount of time trying to figure out why.

Can I clarify here.. so crashes DO NOT, by default get submitted to the dashboard? Unless you do react-native run-ios --configuration Release?

It took me a long time via trial and error to figure that one out.
This should be more clearly stated on Firebase Crashlytics site.
Coming from Fabric Crashlytics, you can have crash logging be reported even in debug mode.
