Classes
AnimationState
Animation state for a single node (standalone animations only).
BulkAnimationData <TKey >
Snapshot of the controller's bulk-animation state at a single point in
time, fetched as one unit so render-layer hot paths can avoid the four
separate getter calls (isBulkAnimating, bulkAnimationValue,
bulkAnimationGeneration, isBulkMember) that would otherwise be
needed each layout.
ItemView <K extends Object , Section , Item >
Rich view of a visible item passed to an item builder.
RenderSliverTree <TKey , TData >
Render object for displaying a tree structure as a sliver.
ReorderRenderPort <TKey >
Render-layer contract consumed by TreeReorderController.
SectionedListController <K extends Object , Section , Item >
The imperative engine behind a SectionedSliverList .
SectionedReorderConfig <K extends Object , Section , Item >
Enables and shapes reordering for a SectionedSliverList .
SectionedSliverList <K extends Object , Section , Item >
A header + items sliver. See the library docs for the two forms.
SectionView <K extends Object , Section , Item >
Rich view of a visible section header passed to a header builder.
SlideAnimation <TKey >
Slide animation state for a single node in a FLIP-style reorder.
SliverReorderableTree <TKey , TData >
Declarative drag-and-drop reorderable SliverTree .
SliverTree <TKey , TData >
A sliver that displays a tree structure with support for
expand/collapse animations.
SliverTreeElement <TKey , TData >
Element for SliverTree that creates and manages child elements.
SliverTreeParentData
Parent data for children of RenderSliverTree.
SyncedSliverTree <TKey , TItem >
A sliver widget that declaratively displays a tree and animates changes.
SyncedTreeNode <TKey , TItem >
A node of the nested tree that SyncedSliverTree's default
constructor consumes.
TreeAnimationSpec
A (duration, curve) pair for one animation family.
TreeAnimationStyle
Timing/easing for every animation family in the sliver tree stack.
TreeChildManager <TKey >
Interface for managing child render objects in RenderSliverTree .
TreeController <TKey , TData >
Controller for a SliverTree widget.
TreeDelayedDragHandle
A TreeDragHandle that waits for a long press before lifting the row.
TreeDragHandle
Arms child as a drag handle for the row that encloses it.
TreeDropTarget <TKey >
Resolved semantic drop target for the current pointer position during a
drag.
TreeItemView <TKey , TItem >
Rich view of a visible synced tree node passed to itemBuilder.
TreeNode <TKey , TData >
User-provided data for a tree node.
TreeNodeBuilder <TKey , TData >
A widget that listens to a TreeController but rebuilds only when the
specified node's TreeController.hasChildren or
TreeController.isExpanded answer actually changes.
TreeReorderConfig <TKey >
Everything a declarative tree needs to support drag-and-drop reorder.
TreeReorderController <TKey >
Controls a drag-and-drop reorder over a TreeController .
TreeRowDragScope
Published by each reorderable row; found by TreeDragHandle.build .
TreeSyncController <TKey , TData >
A controller that syncs a TreeController to a desired state using
animated diffs.
Enums
AncestorExpansionMode
How TreeController.animateScrollToKey handles ancestors of the target
key that are currently collapsed.
AnimationType
The type of animation a node is currently undergoing.
TreeAnimationFamily
The animation families a TreeAnimationStyle carries. Declared at the
site that installs an animation and never re-derived downstream.
TreeDropZone
Where the pointer lies relative to a candidate drop-target row.
Typedefs
ItemDragProxyBuilder K extends Object , Section , Item >
= Widget Function(BuildContext context , ItemView <K , Section , Item > view , Widget ?rowChild
Builds the floating drag preview for an item row.
ReorderSemanticsActionsBuilder TKey >
= Map <CustomSemanticsAction VoidCallback Function(TKey nodeKey , Map <CustomSemanticsAction VoidCallback builtIn
Transforms the reorder actions a row exposes to assistive technology.
SectionDragProxyBuilder K extends Object , Section , Item >
= Widget Function(BuildContext context , SectionView <K , Section , Item > view , Widget ?rowChild
Builds the floating drag preview for a section header.
Builds a header widget for a visible section.
SectionItemBuilder K extends Object , Section , Item >
= Widget Function(BuildContext context , ItemView <K , Section , Item > view
Builds a row widget for a visible item.
TreeItemBuilder TKey , TItem >
= Widget Function(BuildContext context , TreeItemView <TKey , TItem > node
Builds a widget for a visible synced tree node.
