InvalidType with Freezed Union/Sealed classes with json serialization in other Freezed classes.

[JoanSchi]

Hi,

I am using Freezed Union/Sealed classes with json serialization in other Freezed classes. In de past this worked fine, but now I get a InvalidType error.

Example:

import 'package:freezed_annotation/freezed_annotation.dart';

part 'model.freezed.dart';
part 'model.g.dart';

@freezed
sealed class Model with _$Model {
  factory Model.first(String a) = First;
  factory Model.second(int b, bool c) = Second;

  factory Model.fromJson(Map<String, dynamic> json) => _$ModelFromJson(json);
}

import 'package:freezed_annotation/freezed_annotation.dart';
import 'package:simple_test/src/model.dart';

part 'test.freezed.dart';
part 'test.g.dart';

@freezed
class Test with _$Test {
  const factory Test({
    required First first,
  }) = _Test;

  factory Test.fromJson(Map<String, Object?> json) => _$TestFromJson(json);
}

Error
Could not generate fromJson code for first.
To support the type InvalidType you can:

• Use JsonConverter
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonConverter-class.html
• Use JsonKey fields fromJson and toJson
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonKey/fromJson.html
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonKey/toJson.html
  package:simple_test/src/test.freezed.dart:99:21
  ╷

Expected behavior
