currentAnchorKey property

String? get currentAnchorKey

The anchorKey of the step currently on screen, or null when no guide is showing. Lets a DigiaAnchor tell whether it hosts the visible step as it leaves the tree, so navigating off that screen can tear the guide down.

Implementation

String? get currentAnchorKey =>
    (_currentShownIndex >= 0 && _currentShownIndex < _activeAnchorKeys.length)
        ? _activeAnchorKeys[_currentShownIndex]
        : null;
