endlessStreamingRecognize no result after a minute

[MarkZhongsh]

Describe the bug
called "endlessStreamingRecognize" and using stream to add audio frame, it worked for a minute, but all the callbacks(onData, onError, onDone) would not be called. And console in google show that errors 100%.

Expected behavior
should recognize the audio before I call close.

I found that there was no problem if I commented "_resetTimer = Timer(_restartTime, _restart);" in endless_streaming_service.dart.
