sendCommand method
Sends the given command to the back end server. By default the command
will be inserted into the queue and sent after all other previously queued
commands. Setting the instant flag to true will bypass the queue and
send the command immediately. Howver, instant commands will also be lost
if the communicator is not currently connected.
Implementation
Future<void> sendCommand(
DeviceCommand command, {
bool instant = false,
}) async {
if (_active == true) {
if (instant == true && _channel != null) {
_channel!.sink.add(command.toJson());
} else {
_commandQueue.add(command);
await _sendCommands();
}
}
}
