I have a Compose

ModalBottomSheetLayout

where the contents is the main screen with a list of items, and the

sheetContent

are item details (with different settings). As the item details are quite complex, and don't influence the main screen, I would like to have them in a separate ViewModel. How can I pass the

itemId

from the

MainScreenViewModel

to the

ItemDetailsViewModel

. I don't really fancy creating a shared ViewModel just to pass one value (which is anyway only temporary, as the

ItemDetailsViewModel

will store

itemId

as well to get the item data).

Can you have a use-case with a hot-stream variable that would hold currently selected item, and pass that use-case to a

list

and

details

ViewModels?

Thanks for the suggestion. In the end I went with a callback in details ViewModel to set the current item.

We use nested

NavHost

for such bottom panel, so I can get

viewModel

scoped to bottom panel content.
