How did you test this? I tried using android emulator and turning on and off airplane mode, but it seemed like the onDone and onError was never called.

That's exactly what I did, turn off internet, wait for few seconds and turn on again, it works for me. For me onDone was called

hmm so in dartpad the switch expression works and the docs say you just need dart 3.0 for it to work, but it isn't working locally for me on dart 3.3:

did you see this?

I'm sure it's because of this

sdk-for-flutter/pubspec.yaml

Line 16 in f40d4cb

sdk: '>=2.17.0 <4.0.0'

So I will revert it back, as we want it to be compatible with old Dart versions as long as possible.

Here's what I did on emulator

1. Connect and subscribe
2. Disconnect Wifi/Internet (Didn't try Airplane mode, but it should be same)
3. Wait for few seconds
4. Open wifi again
5. Create document
6. You should see the realtime log update
