🐛 [cloud_firestore web] There is no line number for the original firestore call on a "permission-denied" exception

[bernaferrari]

When permission-denied exception is triggered, Flutter doesn't show the origin point (the firebase call that triggered it), so I have no idea which method I should fix.

Ideally, it would show:
file/firebase.dart 1234:56 callFirebase

The following FirebaseException was thrown:
[cloud_firestore/permission-denied] Missing or insufficient permissions.

When the exception was thrown, this was the stack:

Hi @bernaferrari
Could you please provide your flutter doctor -v and flutter pub deps -- --style=compact?
So is this from crashlytics or are you able to reproduce the error?
Thank you

I'm using cloud_firestore: ^2.4.0. This is a fairly simple bug: just try to read something you don't have access to. The exception is expected. The issue is that there is no origin in the logs. I don't know which method triggered that exception. So it gets EXTREMELY HARD to debug.

Do you mean the original call not being in the stack? This seems like a result of how flutter web handles async errors rather than our plugin code.

Labeling this just in case but I'm not sure there is much we can do to improve the stack trace itself.
