Looks good!
I added some comments, it may look a lot but it's because the PR is a bit big..
Some more general comments:

Some of the comments I wrote general and not specific only to the place I added them, so please re-review the whole PR when fixing.
Please run yarn tsc to verify the typescript is ok
Please add api.json file for the docs.
In general theres no need to pass default values, you get them by default :)
Please add render tests, you can see references in other components.
When adding text + image + button, on a stretch case in the example screen, the result is not so good, see the image:

I think we need the png in 5 sizes to support devices with different densities

where can I get the other sizes from?

+    /**
+     * The background style of the footer
+     */
+    backgroundType?: ScreenFooterBackgrounds | `${ScreenFooterBackgrounds}`;


Nice! the type is well defined 😄
Did you understand why we're doing it?

I've seen it done in other places in ui-lib, I guess it's for letting devs write the literal string or to use an enum which supports changes in the enums value?

+  ItemsFit,
+  Switch,
+  TextField,
+  Slider,


The Slider doesn't work so good, can you try the slider from Incubator?

it seems much more laggy tbh, do we still prefer it?

lidord-wix · 2026-01-08T14:09:18Z

demo/src/screens/componentScreens/ScreenFooterScreen.tsx

+            <Slider
+              value={itemWidth}
+              minimumValue={50}
+              maximumValue={500}


the range is too big IMO, let's decrease the max value

250 is ok or too high/low?

packages/react-native-ui-lib/src/components/screenFooter/index.tsx

+        ? {width: itemWidth, flexShrink: 1, overflow: 'hidden' as const}
+        : {width: itemWidth, maxWidth: '100%' as const};


Please avoid using "as ..." for resolving typing issues, it kinda hack

what's the alternative for it? couldn't find one but seemed to be used throughout the repo.
perhaps using 'ViewStyle'?

After making some mess with git history due to the new pre-push check that denied my branch name, I've managed to do it properly.

the new commits start from 'apply small fixes due to PR comments, move types to different file'.

I've left replies to some comments due to things I wasn't sure about.

Here's what was added in the recent commits here -

small changes due to PR comments
moved keyboard hoisting from useKeyboardHeight hook with to KeyboardAccessibilityView for better visuals as you suggested.
added 5 sizes of gradient into assets folder
added a template of docs api.json file, still need to finish it by uploading examples to the media platform
added render tests
moved types into a separate file
found multiple bugs on android that needed addressing, so hopefully fixed them here (sticky still pushed footer on top of keyboard, hoisted + solid caused the background to render on top of footer etc.)

this was quite a lot and I still miss some work on the docs part, but let me know what you think overall.
