SeoFooter class
A semantic <footer> container for Flutter web apps with SEO-friendly HTML injection.
SeoFooter behaves like a regular Flutter Container
but when running on the web (kIsWeb == true),
it injects an actual <footer> HTML element into the DOM.
This is useful for:
- Adding semantic HTML for better SEO.
- Structuring your web layout to be accessible and crawler-friendly.
Example:
SeoFooter(
padding: EdgeInsets.all(16),
color: Colors.grey[200],
child: SeoText('© 2025 My Company'),
)
When rendered in Flutter Web, this generates:
<footer id="footer_ab12">
<p>© 2025 My Company</p>
</footer>
