- Removed the concept of ephemeral routes. - Renamed the two _MenuRoutes to _PopupMenuRoute and _DropDownRoute. - Added type arguments in various places: - DropDownMenu - _DropDownRoute - _ModalBottomSheetRoute - PopupMenuItem - _PopupMenu - _PopupMenuRoute - Made _ModalBottomSheetRoute, the two ex _MenuRoutes, and _DialogRoute all inherit from ModalRoute, via PopupRoute. - Change "Dropdown" and "DropDown" to "DropDown" consistently. - Made MaterialPageRoute inherit from PageRoute. - Made ModalBarrier not create a box if it's always transparent. - Exposed the Futures on TransitionRoutes. - Fixed that menus were no longer dismissable by tapping the modal barrier.
