  String userProfileImage,
  String userFirstName,
  String userLastName}) async {
 try {
  final transaction = MultiAccount()

    ..userFirstName = userFirstName
    ..userLastName = userLastName
    ..userFullName = userFullName
    ..userToken = userToken
    ..userProfileImage = userProfileImage;

  final box = Boxes.getTransactions();
  final transactions = box.values.toList().cast<MultiAccount>();
  bool res = checkDataExist(transactions, userId);
  if (res == false) {
