Required a bool value to prefer disabling the drag from the whole page and allowing only from the revealed part of the screen and the icon.
When set to true, it will ignore any gesture arenas inside the container pages allowing them to work properly. However the page will still be draggable from non gesture arenas.
At least one of the slideIconWidget or enableSideReveal must be there for this to work.
Set this to true if facing problems in giving gesture controls inside the pages
final bool preferDragFromRevealedArea;
