I'm using a LazyVerticalGrid to show a bunch of cards, but I want to fill the "empty" slots in the last row (if any) to have a dummy element. How would I set this up?

It's just a bit of math really.

N = number of items
C = number of columns (you'd know this if you use GridCells.Fixed, otherwise can be calculated via screen width)

F = fraction; (N / C) % 1
R = remaining; C - floor(F * C)

e.g. N = 5, C = 3
F = 0.67
R = 3 - 2 => you need to draw 1 empty item

How would I get the screen width in Compose for Web?

There must be some native delegate, otherwise use BoxWithConstraints

you can implement GridCells interface directly instead of using GridCells.Fixed. In this interface you get the available size and returning the sizes for the cells
