The onDone method could not be called when the connection is broken In LTE.

I found something wrong, maybe it's a bug of the channel. The thing is that When the channel connecting with LTE, it is ok. But later I have closen the LTE. The stranger thing appeared. The onDone method was not called. I think it 's a bug of the web_socket_channel. But When using the Wifi, I didn't find the situation. The problem above in my real phone did not exist. Just in simulator.
