@Composable
fun animateIntOffsetAsState(
    targetValue: IntOffset,
    animationSpec: AnimationSpec<IntOffset> = intOffsetDefaultSpring,
    label: String = "IntOffsetAnimation",
    finishedListener: ((IntOffset) -> Unit)? = null
): State<IntOffset>

Fire-and-forget animation function for IntOffset. This Composable function is overloaded for different parameter types such as Dp, Color, Offset, etc. When the provided targetValue is changed, the animation will run automatically. If there is already an animation in-flight when targetValue changes, the on-going animation will adjust course to animate towards the new target value.

animateIntOffsetAsState returns a State object. The value of the state object will continuously be updated by the animation until the animation finishes.

Note, animateIntOffsetAsState cannot be canceled/stopped without removing this composable function from the tree. See Animatable for cancelable animations.

@Composable
fun OffsetAnimation(selected: Boolean) {
    // Animates the offset depending on the selected flag.
    // [animateOffsetAsState] returns a State<Offset> object. The value of the State object is
    // updated by the animation. Here we use that State<Offset> as a property delegate.
    val offset: Offset by
        animateOffsetAsState(if (selected) Offset(0f, 0f) else Offset(20f, 20f))

    // In this example, animateIntOffsetAsState returns a State<IntOffset>. The value of the
    // returned
    // State object is updated by the animation.
    val intOffset: IntOffset by
        animateIntOffsetAsState(if (selected) IntOffset(0, 0) else IntOffset(50, 50))
}
Parameters
targetValue: IntOffset

Target value of the animation
animationSpec: AnimationSpec<IntOffset> = intOffsetDefaultSpring

The animation that will be used to change the value through time. Physics animation will be used by default.
label: String = "IntOffsetAnimation"

An optional label to differentiate from other animations in Android Studio.
finishedListener: ((IntOffset) -> Unit)? = null

An optional end listener to get notified when the animation is finished.
Returns
State<IntOffset>

A State object, the value of which is updated by animation.
