ModalBottomSheetLayout sheetContent never leaves composition. is tracking offset the only way to observe is it visible or not?

there is a ModalBottomSheetState#isVisible property to check if the bottomSheet is currently visible or hidden https://developer.android.com/reference/kotlin/androidx/compose/material/ModalBottomSheetState#isVisible(). Also, you can use `currentValue`(that is used by isVisible under the hood) to check for the intermediate states like HalfExpanded .

thanks.
I should’ve make myself more clear.
I need something observable state.

isVisible reads from currentValue which is backed by snapshot state. If you read isVisible in any context that tracks state reads (Composition or i.e. snapshotFlow) you will receive updates to it 🙂
