Remember RevealState with additional key

[zak01011996]

Hello, it will be great to have "key" argument in rememberRevealState function. Due to directions are now being handled by state I didn't find a way to update this set dynamically (in case if entry related to this card has been changed for example).

The problem is that there are no ways to "reload" the state by some condition. So here is my workaround for that:

@Composable
fun rememberRevealState(
    key: Any? = Unit,
    maxRevealDp: Dp = 75.dp,
    directions: Set<RevealDirection> = setOf(RevealDirection.StartToEnd, RevealDirection.EndToStart),
    initialValue: RevealValue = RevealValue.Default,
    positionalThreshold: (totalDistance: Float) -> Float = { distance: Float -> distance * 0.5f },
    velocityThreshold: (() -> Float)? = null,
    snapAnimationSpec: AnimationSpec<Float> = tween(),
    decayAnimationSpec: DecayAnimationSpec<Float> = exponentialDecay(),
    confirmValueChange: (newValue: RevealValue) -> Boolean = { true }
): RevealState {
    val density = LocalDensity.current
    return remember(key) {
        RevealState(
            maxRevealDp = maxRevealDp,
            directions = directions,
            density = density,
            initialValue = initialValue,
            positionalThreshold = positionalThreshold,
            velocityThreshold = velocityThreshold ?: { with(density) { 100.dp.toPx() } },
            snapAnimationSpec = snapAnimationSpec,
            decayAnimationSpec = decayAnimationSpec,
            confirmValueChange = confirmValueChange
        )
    }
}

Usage example: In this example if an entry is published I should provide options via StartToEnd direction. If it's not published yet options are on the end of the card to publish this entry first.

   val entry = MyObjectEntry(...)

    val directions = setOf(
        when (entry.isPublished()) {
            true -> RevealDirection.StartToEnd
            false -> RevealDirection.EndToStart
        }
    )

    val state = rememberRevealState(
        key = entry,
        directions = directions,
        maxRevealDp = 100.dp
    )
