12/27/2020, 10:20 PMI am using a ScrollableColumn in an embedded ComposeView in a Fragment, but it is not scrolling all the way to the bottom as it should. I am sure it is sized properly, since I inserted the same way as the RecyclerView it replaces, and that works fine. Here is an example: the ‘time views’ are all locked to a constant height, so I would expect this to be okay.
Has anybody else seen any issues with the ScrollableColumn like this?

12/28/2020, 12:19 AMPerhaps it could be a timing issue, where the ComposeView is grabbing the size before it is fully rendered or attached to the Fragment?

12/28/2020, 1:36 PMi know what you mean, but I am not using scaffold or bottom bar in compose - just the inner content view of the fragment. everything else is standard xml using constraintlayout, with the composeview aligned with navbar and bottom tab bar.

12/29/2020, 10:25 PMI built a small sample project that shows the issue. It appears that the ComposeView, even when embedded in a Fragment, is somehow using the display size to calculate height/scrolling area. I will see if I can post a bug to the compose bug tracker…
