Call onClosed or provide an onStopped method to be called when the connection is stopped in certain cases

Is there an existing issue for this?

Describe the bug

I was running a Flutter app that uses on its android side the signalr java client.
In the android side (the java client), I listen to the onClosed callback from the java client to schedule automatice reconnects in my app.
I was doing a heavy download on my wifi network which was taking the bandwidth from all other apps including my app mentioned above, so the activatePingTimer method appears to have timedout and called the private stop method.
The problem is that this private stop method, does not call the onClosed callback registered by my app, so my app never knew the connection was closed so that it can reschedule an auto-reconnect.
I know that the onClosed callback is documented as

Registers a callback to run when the connection is closed.

But does not this case indicate that connection is closed?
If this is a bug, then the private stop method should call the onClosed callbacks.
Else if this is how its intended to work, then can you provide a way to listen to when the connection stops?
(Whats the difference anyway between "stop" and "close", other than that "close" disposes the resources associated with the object?)
