No clean solution for Firestore + Flutter with offline access

[Jagannathan Srinivasan]

I'm using Cloud Firestore package but none of the Firestore operations work reliably if phone is offline, despite everything the documentation says. I'm quite frustrated that I have to keep checking for internet connectivity before issuing any Firestore calls. I should be able to make the Firestore calls the same way and I expect the calls to fall back on to local cache if there's no connection, else the calls should transparently go online. Is this too much to expect, given all the documentation? Or am I doing something seriously wrong?

Make sure offline persistence is enabled. If it is, this is probably a bug.

I explicitly enabled offline persistence (though documentation says this is enabled by default on Android) The same behavior persists. Looks like Android/Java has mechanisms to handle it since we can trap Snapshot events that returns success/failure depending on whether the device is online. But there's no such thing in Flutter / Cloud Firestore, hence I'm getting this unpredictable/inconsistent behavior.

Does this happen on both Android and IOS? Are you using the latest version of the plugins? I think you might have to migrate to AndroidX too.
