ShoppingItemModel에 copyWith 메서드를 작성하여 toggle 관련 함수 코드를 간결화하는 방법

// select_provider.dart
toggleHasBought(){
    state = ShoppingItemModel(
      name: state.name,
      quantity: state.quantity,
      hasBought: !state.hasBought,
      isSpicy: state.isSpicy,
    );
  }

shopping_item_model.dart 내의 ShoppingItemModel에 copyWith 메소드를 추가

// shopping_item_model.dart
ShoppingItemModel copyWith({
  String? name,
  int? quantity,
  bool? hasBought,
  bool? isSpicy,
}) {
  return ShoppingItemModel(
    name: name ?? this.name,
    quantity: quantity ?? this.quantity,
    hasBought: hasBought ?? this.hasBought,
    isSpicy: isSpicy ?? this.isSpicy,
  );
}

copyWith 메소드를 사용하여 코드를 간결화

// select_provider.dart
  toggleHasBought() {
    state = state.copyWith(
      hasBought: !state.hasBought,
    );
  }
