[sponsored] customAnimation callback is not called when customAnimation changes

[altarrok]

Describe the bug When customAnimation callback is changed, the Carousel does not call customAnimation to get updated values. I am trying to make a scaling animation when the carousel is focused. Here is my code:

    const focusedItemScale = useSharedValue(0.8);

    useEffect(() => {
        focusedItemScale.value = withTiming(carouselFocused ? 1 : 0.8, { duration: 1000, easing: Easing.linear });
    }, [carouselFocused]);

    const customAnimation = useCallback(
        (value: number) => {
            'worklet';

            const zIndex = interpolate(value, [-1, 0, 1], [10, 20, 30]);
            const translateX = interpolate(
                value,
                [-1, 0, 1],
                [-itemGap, 0, itemGap],
            ) + centerOffset;

            const scale = interpolate(
                value,
                [-1, 0, 1],
                [0.8, focusedItemScale.value, 0.8],
            );

            return {
                transform: [{ translateX }, { scale }],
                zIndex,
            };
        },
        [focusedItemScale.value],
    );

So the callback is updated when focusedItemScale.value changes, which does so through a timing animation, when the carouselFocused prop is changed. I would expect the Carousel component to call the customAnimation callback when it changes, to get updated values.

To Reproduce Steps to reproduce the behavior:

1. Using Android
2. Create a custom animation callback function that depends on another animated value (will refer to this as X)
3. Update the animated value (X) using useEffect, depending on a prop
4. Observe that when the animated value (X) is updated, the changes are not reflected to the Carousel

Expected behavior I would expect the Carousel to call the customAnimation callback whenever it changes to get updated values
