Implementation

Future<void> sendMessage(dynamic roomId, String text,
    {bool? ack, String? to, List<String>? tos}) async {
  if (setupDone) {
    var message = {
      'transaction': randomString(),
      "textroom": "message",
      "room": roomId,
      "text": text,
      "to": to,
      "tos": tos,
      "ack": ack
    }..removeWhere((key, value) => value == null);
    _handleRoomIdTypeDifference(message);
    _context._logger
        .fine('sending text message to room:$roomId with payload:$message');
    await this.sendData(stringify(message));
  } else {
    _context._logger.shout(
        'method was called before calling setup(), hence aborting further operation.');
    throw "method was called before calling setup(), hence aborting further operation.";
  }
}
