I am setting up my Flutter project with Firebase. I have setup it using flutterfire configure and I can see the firebase.json was created inside my app’s root directory.

I can launch my Android app with no issue and I can see my Crashlytics reports coming in for Android. The problem is with iOS app, when I want to launch the app, I am getting below error:

Unhandled exception:

Any idea on why this is happening?
