SeoColumn class
A SEO-friendly equivalent of Flutter's Column widget.
This widget behaves like Flutter's Column in the Flutter UI,
but when running on the web, it also injects a <div> container
with display: flex and flex-direction: column into the HTML DOM.
Features:
- Supports all basic Column alignment parameters.
- Injects semantic HTML for better SEO and accessibility.
- Works with children that implement either SeoInjectable or SeoInjectableLayout.
Example:
SeoColumn(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
SeoText('Title'),
SeoButton(text: 'Click Me', onPressed: () {}),
],
)
