Sample Code Snippets

Below are sample snippets to make your blog more technical and developer-friendly.

1. Flutter UI Code for Product List Page

import 'package:flutter/material.dart';

class ProductListPage extends StatelessWidget {
final List> products = [
{"name": "Winter Jacket", "price": 49.99, "image": "assets/jacket.png"},
{"name": "Running Shoes", "price": 79.99, "image": "assets/shoes.png"},
];

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Shop Now")),
body: GridView.builder(
padding: EdgeInsets.all(12),
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
childAspectRatio: 0.65,
),
itemCount: products.length,
itemBuilder: (context, index) {
final product = products[index];
return Card(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(12)),
child: Column(
children: [
Image.asset(product["image"], height: 120),
SizedBox(height: 10),
Text(product["name"], style: TextStyle(fontSize: 16, fontWeight: FontWeight.bold)),
Text("\$${product['price']}", style: TextStyle(color: Colors.green)),
ElevatedButton(
onPressed: () {},
child: Text("Add to Cart"),
),
],
),
);
},
),
);
}
}

2. Node.js Express API for Cart Management

const express = require("express");
const router = express.Router();

let cart = [];

router.post("/add-to-cart", (req, res) => {
const { productId, quantity } = req.body;
const item = { productId, quantity };
cart.push(item);
res.json({ success: true, message: "Item added to cart", cart });
});

router.get("/cart", (req, res) => {
res.json(cart);
});

router.delete("/remove/:id", (req, res) => {
const id = req.params.id;
cart = cart.filter(item => item.productId !== id);
res.json({ success: true, message: "Item removed", cart });
});

module.exports = router;

3. MongoDB Product Schema for eCommerce App

const mongoose = require("mongoose");

const productSchema = new mongoose.Schema({
name: String,
price: Number,
description: String,
stock: Number,
images: [String],
category: String,
ratings: Number,
createdAt: { type: Date, default: Date.now }
});

module.exports = mongoose.model("Product", productSchema);
