Flutter, как преобразовать объект модели в другую модель, чтобы сохранить его в HIVE

Question

У меня есть ответ API, я проанализировал его с помощью ProductsModel, и я пытаюсь сохранить его в моем локальном хранилище с помощью Hive, и у меня другая модель под названием LocalProductsModel. Как я могу привести модель продуктов ответа к LocalProductsModel? Я использовал product.cast ();

Вот моя модель продуктов

  class ProductsList{
      final List<ProductsModel> products;
      ProductsList({this.products});
      factory ProductsList.fromJSON(List<dynamic> parsedJson){
        List <ProductsModel> productsList = new List<ProductsModel>();
        productsList = parsedJson.map((i) => ProductsModel.fromJSON(i)).toList();
        return new ProductsList(
          products: productsList
        );
      }
    }
    class ProductsModel {
      final int id;
      final String name;
      final String catalog_visibility;
      final String description;
      final String short_description;
      final String price;
      final String regular_price;
      final String sale_price;
      final String date_created;

      final List<CategoriesModel> categories;
      final List<ImagesModel> images;
      ProductsModel(
          {this.id,
          this.name,
          this.catalog_visibility,
          this.description,
          this.short_description,
          this.price,
          this.regular_price,
          this.sale_price,
          this.date_created,
          this.categories,
          this.images
          });

      factory ProductsModel.fromJSON(Map<String, dynamic> parsedJson) {
        var categoriesList = parsedJson['categories'] as List;
        var imagesList = parsedJson['images'] as List;
        List<ImagesModel> dataImages = imagesList.map((i) => ImagesModel.fromJSON(i)).toList();
        List<CategoriesModel> dataCategories =
        categoriesList.map((i) => CategoriesModel.fromJSON(i)).toList();
        return ProductsModel(
          id: parsedJson['id'],
          name: parsedJson['name'],
            catalog_visibility: parsedJson['catalog_visibility'],
            description: parsedJson['description'],
            short_description: parsedJson['short_description'],
            regular_price: parsedJson['regular_price'],
            sale_price: parsedJson['sale_price'],
            date_created: parsedJson['date_created'],
            categories: dataCategories,
          images: dataImages
        );

      }

      Map<String, dynamic> toMap() {

        var map = new Map<String, dynamic>();
        ImagesModel img = ImagesModel();
        map["id"] = id;
        map["name"] = name;
        map["description"] = description;
        map["catalog_visibility"] = catalog_visibility;
        map["short_description"] = short_description;
        map["regular_price"] = regular_price;
        map["sale_price"] = sale_price;
        map["date_created"] = date_created;
        map['images'] = this.images.map((v) => v.toMap()).toList();
        return map;
      }
    }

    class CategoriesModel {
      final int id;
      final String name;

      CategoriesModel({this.id, this.name});
      factory CategoriesModel.fromJSON(Map<String, dynamic> parsedJson) {
        return CategoriesModel(id: parsedJson['id'], name: parsedJson['name']);
      }

      Map<String, dynamic> toMap() {

        var map = new Map<String, dynamic>();
        map["id"] = id;
        map["name"] = name;
        return map;
      }
    }

    class ImagesModel{
      final int id;
      final String src;
      final String name;

      ImagesModel({this.id, this.src, this.name});
      factory ImagesModel.fromJSON(Map<String, dynamic> parsedJson){
        return ImagesModel(
          id: parsedJson['id'],
          src: parsedJson['src'],
          name: parsedJson['name']
        );
      }
      Map<String, dynamic> toMap() => {
        "id": id,
        "src": src,
        "name" :name,
      };

У меня есть рабочая функция добавления улей, но я знаю, что это неправильно, потому что я не привел его к моей LocalProductsModel

postCartLocal(ProductsModel products){

     Map<String, dynamic> productsMap = products.toMap();
    Hive.box('cart').add(productsMap);
  }

Когда я получаю значение, я получил тип ошибки '_InternalLinkedHashMap 'не является подтипом типа' LocalProductsModel 'в приведении типа

Мой код при получении значения в локальном хранилище

 Widget _buildListView(){
    return ValueListenableBuilder(
      valueListenable: Hive.box('cart').listenable(),
      builder: (context, snapshot, widget){
        return ListView.builder(
          itemCount: snapshot.length,
            itemBuilder: (context, index) {
            final cart = snapshot.getAt(index) as LocalProductsModel;

            print('lenght ${cart.name}');

            });
      }
    );
  }
