DualTransitionBuilderModifier class

A transition builder that animates its child based on the AnimationStatus of the provided animation.

This widget can be used to specify different enter and exit transitions for a child.

While the animation runs forward, the child is animated according to forwardBuilder and while the animation is running in reverse, it is animated according to reverseBuilder.

Using this builder allows the widget tree to maintain its shape by nesting the enter and exit transitions. This ensures that no state information of any descendant widget is lost when the transition starts or completes.
