         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
