ClientDisconnectedError

While the application was in the foreground, the following error occurred in the log records. It wasn't in the background.

Fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: ClientDisconnectedError

Hello, it seems that this error is thrown when client tries to send pong to closed connection. Does the connection stops working (not reconnecting) after that?

[furkanKotic]

No. It works because I can still get messages even though the error occurs.

[FZambia]

I see, in general it's normal that connection errors happen. And if SDK successfully reconnected - then it's an expected normal behaviour. Probably we should handle and suppress this error in the SDK when sending pong 🤔

[furkanKotic]

It seems to be ok as the message transmission is not interrupted but it is a bit sad to see this in Firebase. I will be happy if improvement is made. thanks

I am also getting the error. Though I get the following information:- Client Connecting

Its something we see very often in our Sentry logging. A bit frustrating as these errors take up a lot of our Sentry allowance (50k per month) and I think we're using the Dart SDK correctly 😕

I can see this being a bit confusing to users of the SDK as when you Google this error, all results point to the SDK being used incorrectly (i.e. not connecting/reconnecting between Foreground)

Trying to address this in #79

[FZambia]

Please let me know whether v0.9.4 fixes this.

[TomBeckett]

@FZambia We've pulled this into our app and are pushing to production soon. Will let you know if we see an improvement. We've not forgotten about it 😃

[furkanKotic]

Significantly reduced log records. We can say the problem is solved.
Thanks 😃

@TomBeckett hello, still waiting for the feedback about your use case, do you have any updates?
