Hi @Ahmedtaha123
Can you please provide your flutter doctor -v, your flutter run --verbose while running on simulator and a minimal complete reproducible code sample.
Thank you

Hey @TahaTesser, I have a similar problem. The output of my flutter doctor -v is:

I tried the same on flutter's master branch which doesn't compile and on stable which causes the same error.

The issue's stacktrace is:

I guess the problem is in this part of the code (status.h, l.80 ff.):

  /// Returns true iff the status indicates success.
  bool ok() const {
    return state_ == nullptr;
  }

It causes Thread 34: EXC_BAD_ACCESS (code=1, address=0xffffffffffffffc0)

This happens anytime I try to access firestore.

I use the following google/firebase-related plugins:

  # firebase
  firebase_core: ^0.4.5

  # storage
  firebase_storage: ^3.1.6
  cloud_firestore: ^0.13.7

  # push notifications
  firebase_messaging: ^6.0.16

  # authentication
  firebase_auth: ^0.16.1

  # third-party logins
  google_sign_in: ^4.5.1

My crash is fixed after applying this suggestion: #2751

[Salakar]

Hey this has been fixed as part of #2582 / #2913 - pending release.
