SeoAwarePage<T extends StatefulWidget> mixin

Mixin for StatefulWidget pages that need SEO metadata.

Provides a declarative way to define SEO properties for a page without using the SeoHead widget.

class ProductPage extends StatefulWidget {
  final String productId;
  const ProductPage({required this.productId});

  @override
  State<ProductPage> createState() => _ProductPageState();
}

class _ProductPageState extends State<ProductPage> with SeoAwarePage {
  @override
  String get seoTitle => 'Product ${widget.productId}';

  @override
  String get seoDescription => 'Details for product ${widget.productId}';

  @override
  String? get seoCanonicalUrl =>
      'https://example.com/products/${widget.productId}';

  @override
  Widget build(BuildContext context) {
    return Scaffold(...);
  }
}
