SeoInitializer class

A widget that ensures a hidden SEO-friendly HTML container exists in the DOM.

This container is used to store HTML elements injected by other SeoInjectable widgets (e.g., SeoImage) so that search engines can read and index them when running on the web.

Flutter web apps render primarily in a <canvas> element, which is not readable by search engine crawlers. By creating a <div id="seo-content" style="display:none">, this widget provides a place where real HTML can be appended for SEO purposes.

Example usage:

void main() {
  runApp(
    SeoInitializer(
      child: MyApp(),
    ),
  );
}

In this example, the hidden #seo-content container will be created automatically when running on the web.
