Is there is a way to see all items on the LazyColumn?

could you please elaborate what do you mean?

When I have Bottom Bar for the Bottom Navigation, It is hiding some items when it stopped scrolling least half way.

do you use Scaffold? there is a padding param is Scaffold’s content composable, which you could apply as contentPadding for LazyColumn

Yes, I do for BottomBar, AppBar and content.
