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>
