I am using ModalBottomSheetLayout and BottomSheetNavigator and I’d like my bottom sheets to open into Expanded state. The HalfExpanded state doesn’t really suit my use case as there is often a lot of content in the sheet, and/or the keyboard is up.

But, curiously, ModalBottomSheetState.expand() is internal and it’s not obvious to me how I could manipulate SwipeableState.anchors .

Any advice? Thanks!

I’m wondering if I might be better served by using BottomSheetScaffold

This is because whether the sheet should be half-expanded or expanded is just an implementation detail right now; the only intention you can express is to show the sheet. Right now it's not really possible to do this but it will be possible to configure your ModalBottomSheetLayout soon (CL: https://android-review.googlesource.com/c/platform/frameworks/support/+/1891098, just need to update a small thing).

RE: BottomSheetNavigator - you shouldn't be using a ModalBottomSheetState explicitly if you are using Accompanist Nav Material, prefer using rememberBottomSheetNavigator which sets this up for you. By holding a ModalBottomSheetState on your own, you are risking BottomSheetNavigator getting out of sync if you control it manually - the BottomSheetNavigator constructor that takes the sheet state will be made internal soon too to avoid this.

Once we merge the CL upstream in Material, I'll add an API for this asap in Accompanist. (Hopefully something like end of next week or the week after)

Oh, also, issue is here: https://issuetracker.google.com/issues/186669820

fwiw if you are in fact in control of the state, you can use animateTo(ModalBottomSheetValue.Expanded instead of expand()

Thanks Jossi. I'll keep an eye out for your updates. Thanks for the work on bottom sheets!
