MorphingListBuilder<T extends Object> class

A high-level builder that integrates MorphingOverlay, OverlayMorphController, MorphingSource, and optionally a grid or carousel preview mode into a single API.

This removes the need for developers to manually wire up controllers, overlays, and morph sources when building spatial interfaces.

Quick Start

MorphingListBuilder<Product>(
  items: products,
  itemBuilder: (context, item, index) => ProductTile(item),
  previewBuilder: (context, item, progress) => ProductPreviewCard(item),
  detailBuilder: (context, item, progress) => ProductDetailScreen(item),
)

Properties

detailBuilder → Widget Function(BuildContext context, T item, double progress)
Builds the fullscreen detail view.
final
enableBlur → bool
Whether to blur the background during expansion.
final
grid → bool
Whether to render the items in a responsive grid layout. If false, uses a standard list view.
final
hashCode → int
The hash code for this object.
no setterinherited
itemBuilder → Widget Function(BuildContext context, T item, int index)
Builds the item tile for the grid or list view.
final
items → List<T>
The list of items to display.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxElevation → double
Maximum elevation (shadow depth) for the morphing card.
final
maxRadius → double
Maximum border radius for the morphing card.
final
padding → EdgeInsetsGeometry
Padding applied to the underlying scroll view.
final
previewBuilder → Widget Function(BuildContext context, T item, double progress)
Builds the floating preview card (shown during card/carousel mode).
final
previewCarousel → bool

A representation of the runtime type of the object.
no setterinherited
scrimColor → Color?
Color of the overlay scrim.
final
sharedTagBuilder → String Function(T item)?
A function to provide an optional hero tag for shared element transitions. If provided, MorphShared will automatically be wrapped around the appropriate builders.
final
surfaceColor → Color?
Background color of the morphing container.
final
thumbnailActiveBorderColor → Color?
final
thumbnailBuilder → Widget Function(BuildContext context, T item, int index, bool isActive)?
Optional builder for circular thumbnails in the overlay mode.

thumbnailPadding → EdgeInsets
final
thumbnailSize → double
final
thumbnailSpacing → double
final
titleBuilder → Widget Function(BuildContext context, T item)?
Builds a title/header shown in the overlay mode.
