How to make flutter icons from card display different icons?

Hi Team

I need help, my app is working fine but the issue now is for me to make flutter furniture icons display different images per each card. Let me share my current logic for this, 

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:carousel_slider/carousel_slider.dart';

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
        centerTitle: true,
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.vertical(
            bottom: Radius.circular(30),
          ),
        ),
        actions: [
          IconButton(
            icon: Icon(Icons.person),
            onPressed: () {
              // Action when person icon is pressed
            },
          ),
          IconButton(
            icon: Icon(Icons.favorite),
            onPressed: () {
              // Action when wishlist icon is pressed
            },
          ),
          IconButton(
            icon: Icon(Icons.shopping_cart),
            onPressed: () {
              // Action when cart icon is pressed
            },
          ),
        ],
        bottom: PreferredSize(
          preferredSize: Size.fromHeight(80),
          child: Padding(
            padding: const EdgeInsets.all(8.0),
            child: Row(
              children: [
                Spacer(),
                Expanded(
                  child: Padding(
                    padding: const EdgeInsets.symmetric(horizontal: 8.0),
                    child: TextField(
                      decoration: InputDecoration(
                        prefixIcon: Icon(Icons.search),
                        hintText: 'Search...',
                        filled: true,
                        fillColor: Colors.grey,
                        border: OutlineInputBorder(
                          borderRadius: BorderRadius.circular(60),
                          borderSide: BorderSide.none,
                        ),
                      ),
                    ),
                  ),
                ),
                Spacer(),
              ],
            ),
          ),
        ),
      ),
      body: GridView.count(
        crossAxisCount: 4,
        padding: EdgeInsets.all(16.0),
        children: List.generate(4, (index) {
          return ShoppingCartItem(index: index + 1);
        }),
      ),
      bottomNavigationBar: BottomAppBar(
        child: Container(
          height: 65,
