AnimatedAlign class

Animated version of Align which automatically transitions the child's position over a given duration whenever the given alignment changes.

Here's an illustration of what this can look like, using a curve of Curves.fastOutSlowIn.

For the animation, you can choose a curve as well as a duration and the widget will automatically animate to the new target alignment. If you require more control over the animation (e.g. if you want to stop it mid-animation), consider using an AlignTransition instead, which takes a provided Animation as argument. While that allows you to fine-tune the animation, it also requires more development overhead as you have to manually manage the lifecycle of the underlying AnimationController.

{@tool dartpad} The following code implements the AnimatedAlign widget, using a curve of Curves.fastOutSlowIn.

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