3. Wait for the installation to complete.
4. Import the eShopee UI Kit in your Dart file:

   import 'package:e_shopee_ui_kit/e_shopee_ui_kit.dart';

5. Create a new file for your app's main class, for example, main.dart.
6. Wrap your app's material app with the EShopeeApp widget from the eShopee UI Kit:

   
   import 'package:flutter/material.dart';
   import 'package:e_shopee_ui_kit/e_shopee_ui_kit.dart';

void main() { runApp( ES HopeeApp( title: 'eShopee', home: HomeScreen(), ), ); }

**Customizing the UI Components**

The eShopee UI Kit comes with a wide range of customizable UI components, including:

* Navigation Bar
* Header
* Footer
* Product Cards
* Product List
* Search Bar
* Sort Filter
* and many more!

To customize these components, you can use various properties and methods provided by the eShopee UI Kit. For example, you can change the navigation bar's background color by using the `navigationBarBackgroundColor` property:
```dart
ESHopeeApp(
  title: 'eShopee',
  home: HomeScreen(),
  navigationBarBackgroundColor: Colors.blue[200],
)

Implementing APIs for Authentication, Product Retrieval, and Payment Processing

To implement APIs for authentication, product retrieval, and payment processing, you can use the eShopee UI Kit's provided APIs. For example, you can use the authenticate API to authenticate the user:

ESHopeeAuthAPI.authenticate(
  email: 'user@example.com',
  password: 'password123',
).then((token) {
  print('Authentication successful, token: $token');
});

Creating a Shopping Cart and Checkout System

To create a shopping cart and checkout system, you can use the eShopee UI Kit's provided widgets, such as the EShopeeCart widget and the EShopeeCheckout widget:

EShopeeCart(
  items: [
    EShopeeCartItem(
      productId: '1',
      quantity: 2,
      price: 19.99,
    ),
    EShopeeCartItem(
      productId: '2',
      quantity: 1,
      price: 9.99,
    ),
  ],
)

EShopeeCheckout(
  items: cart.items,
  total: cart.total,
  submitButton: Text('Place Order'),
)

Customizing the Theme and Colors

To customize the theme and colors, you can use the eShopee UI Kit's provided theme and color APIs. For example, you can change the theme's primary color by using the theme property:

ESHopeeApp(
  title: 'eShopee',
  home: HomeScreen(),
  theme: ESHopeeTheme(
    primaryColor: Colors.red[300],
  ),
)
