MorphingSource<T extends Object> class

Wraps a widget to act as a morph source for the overlay carousel.

On tap, captures the widget's global rect via its RenderBox and calls OverlayMorphController.selectItem with the rect, item data, and index.

Place this around each grid/list item that should trigger the overlay morph.

Usage

GridView.builder(
  itemBuilder: (context, index) {
    return MorphingSource<Product>(
      controller: overlayController,
      item: products[index],
      itemIndex: index,
      child: ProductCard(products[index]),
    );
  },
)
