Jetpack Compose version: 1.4.3

Jetpack Compose component used: BottomSheetScaffold

Android Studio Build: Flamingo | 2022.2.1 Patch 2

Kotlin version: 1.8.10

Steps to Reproduce or Code Sample to Reproduce:

With previous versions of material compose BottomSheetScaffold it was possible to access BottomSheetState targetValue and use it like below.

@ExperimentalMaterialApi
val BottomSheetState.expandProgress: Float
    get() = when {
        currentValue == Collapsed && targetValue == Collapsed -> 0f
        currentValue == Expanded && targetValue == Expanded -> 1f
        currentValue == Collapsed && targetValue == Expanded -> progress.fraction
        else -> 1f - progress.fraction
    }

With newest versions is not possible anymore since targetValue is not exposed anymore (see below), so it is a breaking change that prevents us from updating to latest compose versions.

class BottomSheetState(
    initialValue: BottomSheetValue,
    animationSpec: AnimationSpec<Float> = SwipeableDefaults.AnimationSpec,
    confirmValueChange: (BottomSheetValue) -> Boolean = { true }
) {
    internal val swipeableState = SwipeableV2State(
        initialValue = initialValue,
        animationSpec = animationSpec,
        confirmValueChange = confirmValueChange
    )

    val currentValue: BottomSheetValue
        get() = swipeableState.currentValue

    /**
     * Whether the bottom sheet is expanded.
     */
    val isExpanded: Boolean
        get() = swipeableState.currentValue == Expanded

    /**
     * Whether the bottom sheet is collapsed.
     */
    val isCollapsed: Boolean
        get() = swipeableState.currentValue == Collapsed
