VoidCallback? onLongPress

The handler for SemanticsAction.longPress.

This is the semantic equivalent of a user pressing and holding the screen with the finger for a few seconds without moving it.

VoiceOver users on iOS and TalkBack users on Android can trigger this action by double-tapping the screen without lifting the finger after the second tap.
