Remove web condition to show rail bar

[marcelpinto]

When adding the sideBarOptions the bottom bar does not show anymore, but the sideBarOptions only work for web. This is not really intuitive and I don't see why the railbar should not be used for large screen besides web.

switch ((kIsWeb, widget.sideBarOptions)) this switch should remove the kIsWeb
