replace this with nullable approach:
value?.isEmpty == true
| class ProductDetailScreen extends StatelessWidget { | ||
| static const routeName = '/product-detail'; | ||

may I know why this is nullable? Is there a chance that this can be optional?
| Widget build(BuildContext context) { | ||
| final productsData = Provider.of<ProductsProvider>(context); | ||
| final products = showFavs ? productsData.favoriteItems : productsData.items; | ||
| final products = showFavs! ? productsData.favoriteItems : productsData.items; |
