headingLevel property
final
The heading level in the document structure.
Screen readers will use this value to determine which part of the page structure this heading represents. A level 1 heading usually indicates the main heading of a page, a level 2 heading the first subsection, a level 3 is a subsection of that, and so on.
On web, this sets the aria-level attribute (e.g., aria-level="1").
On Android, this sets the isHeading property for accessibility.
