sendCommand method Null safety
This is the lower level send that transmits the command supplied on the
websocket, It requires a payload
, the command as a Map that will be json
encoded in the format required by OBS, and the args
. Both are combined
into a single Map that is json encoded and transmitted over the websocket.
Implementation
String sendCommand(Map<String, dynamic> payload,
[Map<String, dynamic>? args]) {
message_id++;
payload['message-id'] = message_id.toString();
if (args != null) {
payload.addAll(args);
}
final requestPayload = jsonEncode(payload);
channel.sink.add(requestPayload);
return message_id.toString();
}
