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

[milaGGL]

Hi @timobaehr, thank you for reporting this issue. Could you please provide a minimal reproducible app for us to debug it?

Besides, you have mentioned that Firestore integration in your app is unchanged since years. I assume you are using crashlytics. Can we pin point the date that error started based on crashlytics? How often it is happening? Are only iOS 12 users are affected?

[timobaehr]

Hi @milaGGL, unfortunately I cannot. I cannot reproduce the bug without iPhone 6 with 12.5.7. The bug was reported via Crashlytics only from my users with iOS 12.5.7. Nine users reported this bug 51 times. Crashes are reported between June, 20 and July, 5. Yesterday no user reported this issue but can happen that they didn't retry.

[milaGGL]

@timobaehr, you have mentioned Firestore integration is unchanged since years, but the SDK version in the issue description is a very recent version(10.10.0). Have you upgraded the SDK in your app recently?

[timobaehr]

@milaGGL I upgrade to latest versions from time to time. I meant the source code, not the version. June, 25 I updated the Flutter plugin from 4.4.5 to 4.8.1.

@timobaehr, You have updated Flutter on June 25th, but the problem began on June 20th, so Flutter update might not be the cause.

With the given information, it is hard to debug the issue. My guess is, since there is no code change, a newly upgraded product might contain a bug, or maybe different products (Firestore, Flutter, iOS 12) have version discrepancies. If we can pin-point which product updates introduced the bug, we might be able to compare the version differences to identify the cause.
