AnimatedSlideModifier 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.
{@tool dartpad} This code defines a widget that uses AnimatedSlide to translate a FlutterLogo up or down by the amount of it's height with each press of the corresponding button.
** See code in examples/api/lib/widgets/implicit_animations/animated_slide.0.dart ** {@end-tool}

- AnimatedPositioned, which, as a child of a Stack, automatically transitions its child's position over a given duration whenever the given position changes.
- AnimatedAlign, which automatically transitions its child's position over a given duration whenever the given AnimatedAlign.alignment changes.
