ScaleTransitionModifier class

Animates the scale of a transformed widget.

Here's an illustration of the ScaleTransition widget, with it's alignment animated by a CurvedAnimation set to Curves.fastOutSlowIn:

{@tool dartpad} The following code implements the ScaleTransition as seen in the video above:
