MorphShared class

A tag-based shared element that animates individually during a morph transition.

Elements with matching tag values across a collapsed and expanded builder are identified by the morph engine and can be animated independently — similar to Flutter Hero but scoped to the morph container.

Usage

// In collapsedBuilder:
MorphShared(
  tag: 'product-image-42',
  child: Image.network(product.imageUrl),
)

// In expandedBuilder (same tag):
MorphShared(
  tag: 'product-image-42',
  child: Image.network(product.imageUrl, fit: BoxFit.cover),
)

When enableSharedElements is true on MorphingCard, the engine will animate matched elements from their collapsed position to their expanded position separately from the container morph.
