sendCommand method

Implementation

@override
Future<String> sendCommand(String receiverId, String strCmd) async {
  var params = <String, dynamic>{};
  params.putIfAbsent("receiverId", () => receiverId);
  params.putIfAbsent("strCmd", () => strCmd);

  return await methodChannel
      .invokeMethod<String>('sendCommand', params)
      .then<String>((String? value) => value ?? "");
}
