Hey Farheen. While reviewing material API and talking about ListItem api, it made sense to us to expect a Surface inside of ListItem, meaning that ListItem is non-transparent and has some background.

However, according to specs (go/material-params), this is not the case and ListItem should have no background and obey the parent background and content-color wise.

I if this scales and works in real apps, as usually it's expected that ListItem has a background. For example:

ListItems could be swipeable (and it needs to have background to swipe and uncover background behind it)
it need to appear/disappear / rearrange when items order changes or item is removed / added. This is usually implies that there's a background on the item that is scaled and animated as a part of ListItem

Given that both 1 and 2 are very common patterns in material, I wonder if material ListItem that we make in compose should also provide Surface underneath by default.

Looking for your opinion and guidance. Thanks!

It's a RAR archive, there's no issue with it.
However you have problems extracting such, here's the same content as a ZIP archive.
