is there any examples using @Implements with json_serializable ?

[heemoe]

Here is the code let me confuse.

import 'package:freezed_annotation/freezed_annotation.dart';

part 'example.freezed.dart';
part 'example.g.dart';

abstract class GeographicArea {
  int get population;

  String get name;

  String get area;
}

@freezed
sealed class Example with _$Example {
  const factory Example.person(
          @JsonKey(name: 'name') String name, @JsonKey(name: 'age') int? age) =
      Person;

  factory Example.fromJson(Map<String, Object?> json) =>
      _$ExampleFromJson(json);

  @Implements<GeographicArea>()
  const factory Example.city(String name, int population) = City;
}

test() {
  // is this correct?
  City a = City.fromJson({
    'name': 'John Smith',
    'age': 42,
  });
}

I don't understand what this is about. Could you be more specific?

[heemoe]

As the code above, can I use City.fromJson for create a object?

[rrousselGit]

Sure that should work.

Thanks for your reply, I do think we need improve the documentation, add more examples will be really helpful.
