Opportunity to attach user feedback to a crash report like in the iOS SDK

[dschmidt1985]

What feature would you like to see?

We need the opportunity to add a user feedback to a crash report, before we send it. With this issue firebase/firebase-ios-sdk#6431 the iOS SDK gets an api to checkAndUpdateUnsentReportsWithCompletion and it would be nice, if the android sdk has a similar opportunity.

How would you use it?

The idea here is, to check after starting of the app if there was a crash in the last run of the app and then we would show the user a dialog to ask for feedback. we want then attach that feedback to the last report and sent it to firebase crashlytics.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
