Not generating other factories when fromJson present

[gullucktheapp]

import 'package:freezed_annotation/freezed_annotation.dart';

part 'income_dto.freezed.dart';

part 'income_dto.g.dart';

@freezed
abstract class IncomeDto with _$IncomeDto {
const factory IncomeDto({
@required String id,
@required num amount,
}) = _IncomeDto;

factory IncomeDto.fromJson(Map<String, dynamic> json) =>
_$IncomeDtoFromJson(json);

factory IncomeDto.unknown(num amount) => IncomeDto(
id: '',
amount: amount,
);
}

Its giving this error

Could not generate fromJson code for copyWith.
To support the type _$IncomeDtoCopyWith 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

@rrousselGit this is only a problem with 0.12.5. @gullucktheapp you might want to use 0.12.4 or lesser version

This was fixed as part of 0.12.6
