sendMessage method

Implementation

void sendMessage() async {
  // isSendButtonEnabled = false; // Listener on messageCtrl handles this

  final text = messageCtrl.text;
  if (text.isEmpty) return; // Prevent sending empty messages
  messageCtrl.clear();
  // notifyListeners(); // Listener on messageCtrl handles this

  final lp = room.localParticipant;
  if (lp == null) return;

  final nowUtc = DateTime.now().toUtc();
  final segment = sdk.TranscriptionSegment(
      id: uuid.v4(), text: text, firstReceivedTime: nowUtc, lastReceivedTime: nowUtc, isFinal: true, language: 'en');
  roomContext.insertTranscription(components.TranscriptionForParticipant(segment, lp));

  await lp.sendText(text, options: sdk.SendTextOptions(topic: 'lk.chat'));
}
