JSON Serialization with relations about objectbox-dart

[badayumut]

I was about to update the issue with that the generated example_model.g.dart did not have the rel convertion methods. Anyway I couldn't make it work this way. So i implemented a custom map for to-from methods. I think it's the best way to it with more control. Thanks!

From what I can see the constructors of the classes you have given do not have parameters for the relation fields:

  Book({
    required this.content, // no parameter for author
  });

  Person({
    required this.name, // no parameter for books
  });

In any case, I would strongly recommend to use a different model for the database and the JSON serializer and map between them. It would avoid this issue and also make any future changes easier to handle.

Let me know if this resolves your issue!
