Creates a stream of the latency in milliseconds from the program to the NT4 server
Implementation
Stream<int> latencyStream() async* {
yield _latencyMs;
int lastYielded = _latencyMs;
while (true) {
await Future.delayed(Duration(seconds: 1));
if (_latencyMs != lastYielded) {
yield _latencyMs;
lastYielded = _latencyMs;
}
}
}
