@noman2002 it seems that ChatUser is not fully serializable.
check the output in here:
{_id: 1, sender: Instance of 'ChatUser', receiver: Instance of 'ChatUser', messageContent: Hello, how are you?}

when I call final json = chatMessage.toJson()

I do have the chat_user.g.dart and chat_message.g.dart files, but still it is not serializing properly. any suggestion?

[noman2002]

@palisadoes Your thought?

[antonio-pedro99]

@noman2002 I do not have experience with object serialization yet, but allow me sometime to learn about it.
My thoughts now are that this should be printed
{_id: 1, sender: {...}, receiver: {...}, messageContent: Hello, how are you?}
as the objects are serializable.

I just took a look at https://docs.flutter.dev/development/data-and-backend/json and found a possible solution.

[noman2002]

@antonio-pedro99 I don't think there is any issue with serialisation. It shows like that because we are using models for that and that is being printed over there as Instance of 'chatuser'.

I just took a look at https://docs.flutter.dev/development/data-and-backend/json and found a possible solution.

Sure go ahead.

[antonio-pedro99]

@noman2002 fixed!

`@JsonSerializable(explicitToJson: true)
class ChatMessage {
ChatMessage(
this.id,
this.sender,
this.messageContent,
this.receiver,
);

factory ChatMessage.fromJson(Map<String, dynamic> json) =>
_$ChatMessageFromJson(json);
Map<String, dynamic> toJson() => _$ChatMessageToJson(this);

String? id;
ChatUser? sender;
ChatUser? receiver;
String? messageContent;
}`

[noman2002]

Great. Have you written the test for it? If yes, check the code coverage, if it is 100%, Please create a PR for it.

@noman2002 how can I check the coverage?
