Flutter Web: aria-expanded must be an available property on elements that toggle visibility of content (Accessibility) #162141
Description
Use case
The aria-expanded attribute is applied to a focusable, interactive element that toggles visibility of content in another element. For example, show/hide or "accordion" elements, combobox elements, listbox elements, and more.
Proposal
Add the WAI-ARIA property aria-expanded to the list of semantics flags on the following element types/widgets. Its value is true when the content is expanded/visible, and false when the content is collapsed/not visible.
