dataclass 오류

Question

dataclass build 하면 아래 오류가 항상 발생하네요 어떤 이유일까요? // Recipe model class import 'package:receipt/domain/model/recipe_ingredient.dart'; import 'package:freezed_annotation/freezed_annotation.dart'; part 'recipe.freezed.dart'; part 'recipe.g.dart'; @freezed class Recipe with $Recipe { const factory Recipe({ required String category, required int id, required String name, required String image, required String chef, required String time, required double rating, required List ingredients, @Default(false) bool isFavorite, }) = Recipe; factory Recipe.fromJson(Map json) => _$RecipeFromJson(json); } --> 오류 Missing concrete implementations of 'getter mixin $Recipe on Object. category', 'getter mixin $Recipe on Object. chef', 'getter mixin $Recipe on Object. id', 'getter mixin $Recipe on Object. image', and 6 more. (Documentation) --> get 생성 시 오류 사라짐 @override // TODO: implement category String get category => throw UnimplementedError(); @override // TODO: implement chef String get chef => throw UnimplementedError(); @override // TODO: implement id int get id => throw UnimplementedError(); @override // TODO: implement image String get image => throw UnimplementedError(); @override // TODO: implement ingredients List get ingredients => throw UnimplementedError(); @override // TODO: implement isFavorite bool get isFavorite => throw UnimplementedError(); @override // TODO: implement name String get name => throw UnimplementedError(); @override // TODO: implement rating double get rating => throw UnimplementedError(); @override // TODO: implement time String get time => throw UnimplementedError(); @override Map toJson() { // TODO: implement toJson throw UnimplementedError(); }

네 지금은 추상클래스로 선언했습니다.

혹시 작성하신 모델클래스 맨 앞에 abstract 가 없다면 붙여주세요. freezed 3.0 부터 문법이 일부 변경되었습니다.
