/// remember to exnted class from DTO for data transmission
/// there we will be transferring Message data over socket

class Message extends DTO {
String username;
String message;

Message({required this.username, required this.message});

factory Message.fromJson(Map<String, dynamic> json) {
return Message(username: json['username'], message: json['message']);
}

@override
Map<String, dynamic> toJson() {
return {"username": username, "message": message};
}

/// in case you wish to encode data differently
/// then remember to decode data correspondingly
@override
String encode() {
return json.encode(toJson());
