Just reading through the

AdapterList

PR, excited to see this start to take shape. I believe Flutter implements their lists on top of a fairly complex “sliver” API which they also use to implement things like fancy Material collapsing AppBars ala

CoordinatorLayout

. Does the Compose team have any thoughts about how to implement collapsing app bars with Compose? (The AdapterList PR is here: https://android-review.googlesource.com/c/platform/frameworks/support/+/1218839)

A(n extremely) rough analog might be subcomposition, which the adapter list is using. Collapsing app bars probably won't need it, but it's there if there's a use case for it for whatever reason
