Feels like some options:
• Custom Column, like modify from source.
• Add DSL into ColumnScope like LazyColumn which automatic add divider between items looped.
• Custom Arrangement. Not sure if arrangement supports compose code or only pixel arrangements. This would be ideal, as could reuse everywhere in Row, Lazy lists etc as well.
• Ask Google add decorator pattern or such similar as we had in RecyclerView or LinearLayout as mentioned.
• Another semi hacky solution, custom layout wrapping Column. Send in list and add divider between each.
• Make custom item compose object hide/show divider top or bottom
I understand what youre after and also wish existed one built in. But a lot easier in compose :)
