FlowPopupAnimator class
A CurvedAnimation preset for the flow_box_popup morph transition.
Wraps a parent AnimationController with configurable forward and reverse
easing curves, defaulting to Cubic(1.0, 0.155, 0.155, 1.0) — a subtle
overshoot similar to easeOutBack for a snappy, modern feel.
Example:
final animator = FlowPopupAnimator(
parent: controller,
curve: Curves.easeInOutQuart,
reverseCurve: Curves.easeOutCubic,
);

- FlowPopupAnimator({required AnimationController parent, Curve curve = const Cubic(1.0, 0.155, 0.155, 1.0), Curve reverseCurve = const Cubic(1.0, 0.155, 0.155, 1.0)})
- Creates a FlowPopupAnimator.
