title: Text('E-commerce App'),
),
body: (
itemCount: 10,
itemBuilder: (context, index) {
return ListTile(
title: Text('Product $index'),
onTap: () {
(
context,
MaterialPageRoute(builder: (context) => ProductDetailPage()),
);
},
);
},
),
);
}
}
```
Creating the Product Detail Screen
1. Create a new widget file named `` in the `lib` directory.
2. Import necessary libraries:
