Issues with wifi and physical device

[gorcsgergely]

Firebase authentication and firestore database operations are not working on Android, but only when a phone is using wifi.
As soon as wifi turned off, works perfectly with mobile data. Tested on multiple devices, multiple networks.
Emulator works perfectly with the same wifi. I don't really know how anybody is able to release any Flutter application using Firebase with that bug.

Did anybody manage to solve it? I see that it is a 2 year old problem.

The same issue is mentioned in numerous places by many people. Also there are closed issues here without any resolution.

I notice this problem a long time ago like YOU (around 2 years). To solve that I build a whole architecture that start to listen a bunch of document when detect if the Firestore returned error code like

PlatformException(Error performing get, Failed to get document because the client is offline., null),

This is sad, because this issue happen a long time, and the worst part is: This is very critical to the users because this issue usually appear when the users are in the most critical part of the applications, in the on-boarding (login).
