Getting Started

• Initialization

  first, create an instance of flutter_cart package.

   // Set [isPersistenceSupportEnabled] to true to turn on the cart persistence
     void main() async {
       WidgetsFlutterBinding.ensureInitialized();
       var cart = FlutterCart();
       await cart.initializeCart(isPersistenceSupportEnabled: true);
       runApp(MyApp());
     }
  

• Add to cart 🛒

       // This method is called when we have to add an item to the cart
       // Example:
       void addToCart(YourProductModel product) {
       flutterCart.addToCart(
         cartModel: CartModel(
           // ... other parameters
           if [discount] is applicable and in percentage so, you can
           calculate the discount like this
           var discount = (product.discountPercentage / 100) * product.price;
           discount: discount,
           [productMeta] takes Map<String, dynamic> so, you can store your complete product data in productMeta
           productMeta: product.toJson()),
         );
       }
  

• Update quantity ➕/ ➖

      // [updateQuantity] is used to increment/decrement the item quantity
      // Example:
      void updateQuantity(CartModel item, int newQuantity) {
         flutterCart.updateQuantity(
         item.productId, item.variants, newQuantity);
      }
  

• Remove item 🗑️

      // [removeItem] is used for removing the specific item from the cart
      // Example:
      void removeItemFromCart(CartModel item) {
        flutterCart.removeItem(item.productId, item.variants);
      }

       void clearCart() {
          flutterCart.clearCart();
       }

      List<CartModel> get getCartItems => flutterCart.cartItemsList;
  

• Total quantity

      int get getCartCount => flutterCart.cartLength;
