Description

After having the app for a while in the background, when I open the app and try to fetch something from firestore I get the following exception from firebase firestore:

Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: Exception: Fetching ads error. Message: PlatformException(firebase_firestore, com.google.firebase.firestore.FirebaseFirestoreException: UNAVAILABLE: Unable to resolve host firestore.googleapis.com, {code: unavailable, message: The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.}, null)

However, it works normally on the second try.

I saw similar error reported for native android in 2022:
https://github.com/firebase/firebase-android-sdk/issues/3302

Reproducing the issue

1. Put app in the background for a couple of hours
2. Open the app
3. Fetch something from firestore

Expected behavior: Data is retrieved
Actual behavior: Exception above occurs:

Firebase Core version

3.8.0

Flutter Version

3.24.4
