Add JSON serializer to every model class?

Question

When it comes to JSON encoding in Dart, per Seth Ladd\'s accouncement the finally approved now official way to go is dart:convert + JSON.Encode.

Answer 1

I wrote the Exportable library to solve such things like converting to Map or JSON. Using it, the model declaration looks like:

import 'package:exportable/exportable.dart';

class Customer extends Object with Exportable {
  @export int id;
  @export String name;
}

And if you want to convert to JSON, you may:

String jsonString = customer.toJson();

Also, it's easy to initialize new object from a JSON string:

Customer customer = new Customer()..initFromJson(jsonString);

Or alternatively:

Customer customer = new Exportable(Customer, jsonString);
