Expression To return Screen type (Phone, Desktop, tab, desktop_wide etc)

Tablet : //docs.appian.com/suite/help/20.1/fnc_scripting_isNativeTablet.html

Phone : https://docs.appian.com/suite/help/20.1/fnc_scripting_isNativePhone.html

a!isNativePhone() and a!isNativeTablet() both functions are deprecated from appian new version.
And these functions will return true/false.
But my requirement is dt it has to return screen type only.

Hi it is not having exact same as you want but please check the stackWhen component on the columns layout https://docs.appian.com/suite/help/22.3/Columns_Layout.html

Edit: You can try this

a!richTextDisplayField(
  value: 
  if(
    a!isPageWidth("PHONE"),
    "PHONE",
    a!isPageWidth("DESKTOP"),
    "DESKTOP",
    a!isPageWidth("DESKTOP_WIDE"),
    "DESKTOP_WIDE",
    a!isPageWidth("DESKTOP_NARROW"),
    "DESKTOP_NARROW",
    "i DONT KNOW"
  )
)

It does seem a bit backwards that we require such a work-around to GET the current page width - to me it seems like there should've just been a "a!pageWidth()" function that RETURNS the current page width, i.e. the inverse of what we have to do with a!isPageWidth.  I assume they have reasons, but...

I suppose it might be helpful to build it in such a way that we could maintain a separate array of valid widths (like in a constant) then have a rule simply iterate over that list and find the valid width (if any).

/* rule!GLBL_getPageWidth() */
a!localVariables(
  local!widths: {
    "PHONE", "TABLET_PORTRAIT", "TABLET_LANDSCAPE", "DESKTOP_NARROW", "DESKTOP", "DESKTOP_WIDE"
  },

  index(
    a!flatten(a!forEach(
      local!widths,
      if(
        a!isPageWidth(fv!item),
        fv!item,
        {}
      )
    )),
    1,
    "Unknown"
  )
)

yes working perfect, Thank you so much
