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

Another package solving this problem is built_value:

https://github.com/google/built_value.dart

With built_value your model classes look like this:

abstract class Account implements Built {
  static Serializer get serializer => _$accountSerializer;

  int get id;
  String get name;
  BuiltMap get keyValues;

  factory Account([updates(AccountBuilder b)]) = _$Account;
  Account._();
}

Note that built_value isn't just about serialization -- it also provides operator==, hashCode, toString, and a builder class.
