1. Incorporate the package in your Dart file:

import 'package:flutter_cart/flutter_cart.dart';

2. Set the ball rolling by initializing the cart:

await FlutterCart().init();

3. You're all set to harness the shopping cart features in your application!

// Add products to the cart
await FlutterCart().addToCart(FlutterCartItem());

// Eliminate a product from the cart
await FlutterCart().removeFromCart(productId);

// Increase the product quantity in the cart
await FlutterCart().incrementCartItemQuantity(productId);

// Reduce the product quantity in the cart
await FlutterCart().decrementCartItemQuantity(productId);

// Fetch the total price of cart items
double totalPrice = FlutterCart().calculateTotalPrice();

// Get the total quantity of cart items
int itemCount = FlutterCart().getCartItemCount();

// Empty the cart
FlutterCart().clearCart();

// Fetch cart data and total price
Map<String, dynamic> cartData = FlutterCart().getCartData();
List<FlutterCartItem> cartItems = cartData['cartItems'];
double totalPriceFromData = cartData['totalPrice'];

FlutterCart().showCartItems(
  cartTileWidget: ({required FlutterCartItem data}) {
    // Your personalized cart item widget
  },
  showEmptyCartMsgWidget: YourEmptyCartMessageWidget(),
);

FlutterCart().showCartItemCountWidget(
  cartItemCountWidgetBuilder: (int itemCount) {
    // Your personalized widget displaying the cart item count
