Which exceptions/errors can we mark as fatal in firebase for flutter?

[hrajwade96]

I am working on a flutter project where I've integrated firebase. I need to report crashes to firebase crashlytics. In flutter however app doesn't exist on crash, screen blacks out disabling functionality. There is a FlutterError handler, Which catches uncaught exceptions in flutter code. But in most cases it also catches non serious exceptions like api failures. I am using a conditional marking of errors and exceptions as fatal/non fatal. Currently i have marked StateError,FormatException,ConcurrentModificationError, and OutOfMemoryError as fatal and rest will be non fatal by default. Is there any general guideline on which error should be marked as fatal. Which more items can i add to this list to mark as fatal?
