MorphingFrame class

A wrapper widget that scales its child when a MorphingCard or MorphOverlayManager within its subtree is active.

Use this at the root of your page (e.g., wrapping the Scaffold or GridView) to achieve the "Background Scale" effect where the background UI shrinks away when a morphing detail view opens.

Example

final controller = MorphController(vsync: this);

MorphingFrame(
  controller: controller,
  child: Scaffold(
    body: GridView.builder(
      itemBuilder: (context, index) => MorphingCard(
        controller: controller, // Share the controller
        ...
      ),
    ),
  ),
)
