I'm trying to see if any in-build animation exist on the design library to create floating action button transforming into single material sheet like shown in the material design image

Add the floating action button to your layoutThe size of the FAB, using the app:fabSize attribute or the setSize() method. The ripple color of the FAB, using the app:rippleColor attribute or the setRippleColor() method. The FAB icon, using the android:src attribute or the setImageDrawable() method.
Designing Custom Expandable FAB After creating a new Android project, go to the drawable folder and import drawable icons from vector assets. These icons will be placed at the center of the FAB. To add icons, right-click on drawable , select new , then select Vector Asset and choose an icon from Clip Art .
Use MaterialContainerTransform from Material Components:
private fun toggleFabMenu() {
val views = listOf<View>(fab, menuView).sortedBy { !it.isVisible }
val shareMenuTransform = MaterialContainerTransform().apply {
startView = views.first()
endView = views.last()
scrimColor = Color.TRANSPARENT
duration = 500
}
TransitionManager.beginDelayedTransition(root, shareMenuTransform)
views.first().isVisible = false
views.last().isVisible = true
}
