AnimatedSizeModifier class

Animated widget that automatically transitions its size over a given duration whenever the given child's size changes.

{@tool dartpad} This example makes a Container react to being touched, causing the child of the AnimatedSize widget, here a FlutterLogo, to animate.

** See code in examples/api/lib/widgets/animated_size/animated_size.0.dart ** {@end-tool}
