AnimatedSlide class

Widget which automatically transitions the child's offset relative to its normal position whenever the given offset changes.

The translation is expressed as an Offset scaled to the child's size. For example, an Offset with a dx of 0.25 will result in a horizontal translation of one quarter the width of the child.

This code defines a widget that uses AnimatedSlide to translate a FlutterLogo up or down and right or left by dragging the X and Y axis sliders.
