AnimationConfiguration class
AnimationConfiguration provides the configuration used as a base for every children Animation. Configuration made in AnimationConfiguration can be overridden in Animation children if needed.
Depending on the scenario in which you will present your animations, you should use one of AnimationConfiguration's named constructors.
AnimationConfiguration.synchronized if you want to launch all the children's animations at the same time.
AnimationConfiguration.staggeredList if you want to delay the animation of each child to produce a single-axis staggered animations (from top to bottom or from left to right).
AnimationConfiguration.staggeredGrid if you want to delay the animation of each child to produce a dual-axis staggered animations (from left to right and top to bottom).

Constructors
- AnimationConfiguration.staggeredGrid({Key? key, required int position, Duration duration = const Duration(milliseconds: 225), Duration? delay, required int columnCount, required Widget child})
-
Configure the children's animation to be staggered.
const
- AnimationConfiguration.staggeredList({Key? key, required int position, Duration duration = const Duration(milliseconds: 225), Duration? delay, required Widget child})
-
Configure the children's animation to be staggered.
const
- AnimationConfiguration.synchronized({Key? key, Duration duration = const Duration(milliseconds: 225), required Widget child})
-
Configure the children's animation to be synchronized (all the children's animation start at the same time).
