Is there a technical reason that there's no material3 bottom sheet destination for navigation, or has it just not been implemented yet?

[Fergus Hewson]

Wouldn't the bottom sheet display based on the state generated from the viewModel for that content?

[eygraber]

It could, but the same question could be asked of the dialog destination.

[Hristijan]

I'm not sure but maybe modal bottom sheet layout needs to be migrated first, no?

We haven't gotten to this yet as other work is higher priority. I'll write a small sample soon, but we recommend implementing a custom navigator (~60 LoC) in the meantime 🙂

@jossiwolf is there some documentation on how to implement custom navigator? I havent found any and I am curious

[eygraber]

@jossiwolf did you ever get a chance to write that sample?

[eygraber]

Well instead of waiting longer I just made my own based off of the dialog navigator - https://github.com/eygraber/vice/pull/198

There's one thing I need to fix which is to provide the navigator annotations for Android, and after that is done I will publish the library (likely tomorrow night).

@eygraber does the parent ModalBottomSheetLayout need M3 migration or no? 🤔

[eygraber]

I'll write up usage in the readme of the new repo, but basically you need to do:

NavHost(...) { ... }
ModalBottomSheetHost()
