VoidCallback? onTap

The handler for SemanticsAction.tap.

This is the semantic equivalent of a user briefly tapping the screen with the finger without moving it. For example, a button should implement this action.

VoiceOver users on iOS and TalkBack users on Android can trigger this action by double-tapping the screen while an element is focused.
