Here's an example code for including a product in a list using Flutter:

class Product {
  final String name;
  final double price;

  Product(this.name, this.price);
}

class ProductList extends StatelessWidget {
  final List<Product> products = [
    Product('Apple', 1.0),
    Product('Banana', 0.5),
    Product('Orange', 0.8)
  ];

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
        itemCount: products.length,
        itemBuilder: (BuildContext context, int index) {
          return ListTile(
            title: Text(products[index].name),
            trailing: Text('\$${products[index].price.toString()}'),
          );
        });
  }
}

In the code above, we define a Product class with name and price properties. We then create a ProductList class with a products list that contains three Product objects.

In the build method, we use a ListView.builder widget to build a list of ListTile widgets, with each tile displaying the name and price of a Product. We use the itemCount property of the ListView.builder to set the number of items in the list, and the itemBuilder property to define how each item should be built.

Ultimately, this results in a list of products being displayed in a Flutter app.
