Have a go hero – Adding an animation of the item's position

You can make the calculator's transition even more appealing if you make the text field fly away off screen while fading out. Just use the form editor to change the text field's position in the single_argument state, and then attach another PropertyAnimation to the Transition object. You can play with different easing types to see which looks better for this purpose.
