DraggableFloatingMenu class

A draggable floating menu widget that leaves the FAB unchanged but dynamically positions the popup menu in one of eight directions. The popup’s fade animation is calculated based on its opacity. Items are built via an itemBuilder callback. Tapping a menu item calls onItemTap with the index of the pressed item.
