What you need to know

  • Microsoft released Fluent UI for Surface Duo.
  • Fluent UI for Surface Duo helps developers create apps that work well on dual-screen devices.
  • Fluent UI controls include things such as "AppBarLayout," which makes sure a search box doesn't extend under the hinge of the Surface Duo.

A devblog post from Microsoft explains all of the Fluent UI controls. There are controls, such as AppBarLayout that stops search inputs from extending under the hinge of devices like the Surface Duo, and DateTimePicker that prevents popups from appearing under a device's hinge.

Here are all of the controls, as outlined by Microsoft:

Swipe to scroll horizontally
ControlDescription
AppBarLayoutSearch input box does not extend under the hinge
BottomSheetAlways appears on the right screen, and never under the hinge
CalendarViewCan be spanned under hinge and day columns adjust
DrawerDrawer appears on a single screen
PeoplePickerViewPersona chips will avoid being placed under the hinge
DateTimePickerPopups will not appear under the hinge
PopupMenuMenus will avoid appearing under the hinge
SnackbarThe snackbar will only show on a single screen, and not appear spanned under the hinge
TooltipTooltips avoid appearing under the hinge

If you want to see what these look like in action, you can look at Microsoft's Fluent UI sample app on GitHub.
