String? arMessage,
Data? data,
int? status,

RegisterResponse.fromJson(dynamic json) {
_success = json['success'];

_arMessage = json['ar_message'];
_data = json['data'] != null ? Data.fromJson(json['data']) : null;
_status = json['status'];
}
bool? _success;
String? _enMessage;
String? _arMessage;
Data? _data;
int? _status;
RegisterResponse copyWith({

bool? get success => _success;
String? get enMessage => _enMessage;
String? get arMessage => _arMessage;
Data? get data => _data;

Map<String, dynamic> toJson() {
final map = <String, dynamic>{};
map['success'] = _success;
map['en_message'] = _enMessage;

if (_data != null) {
map['data'] = _data?.toJson();
}
map['status'] = _status;
return map;
}
}

Answer 1

en_message should have a value in response.
Your enMessage is empty, that's why you didn't get any message.
Use this inside snackbar, if content is not null
registerResponseModel.enMessage
.
