LocalHero class
Mark its child as a candidate for local hero animation.
When the position of this widget (from the perspective of Flutter) changes, an animation is started from the previous position to the new one.
You'll have to use a Key in the top most parent in your container in order to explicitly tell the framework to preserve the state of your children.
