AnimatedPadding class
Animated version of Padding which automatically transitions the indentation over a given duration whenever the given inset changes.
Here's an illustration of what using this widget looks like, using a curve of Curves.fastOutSlowIn.
{@tool dartpad} The following code implements the AnimatedPadding widget, using a curve of Curves.easeInOut.
** See code in examples/api/lib/widgets/implicit_animations/animated_padding.0.dart ** {@end-tool}
