Properties
-
controller
→ TreeController<
TKey, TData> -
The tree controller driving structural state and animations.
final
- draggedOpacity → double
-
Opacity applied to the source row while it is being dragged.
final
- dropIndicatorColor → Color
-
Color of the drop indicator line.
final
- dropIndicatorThickness → double
-
Thickness of the drop indicator line in logical pixels.
final
- hashCode → int
-

no setterinherited
- indentPerDepth → double
-
Horizontal indent used per depth level when positioning the drop
indicator. Should match the indent your nodeBuilder produces.
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- maxStickyDepth → int
-
See SliverTree.maxStickyDepth.
final
- nodeBuilder → Widget Function(BuildContext context, TKey nodeKey, int nodeDepth, ReorderableNodeWrapper wrap)
-
Builds each row. Wrap the row widget with
wrapto enable dragging.final -
reorderController
→ TreeReorderController<
TKey, TData> -
The reorder controller orchestrating the drag lifecycle.
final
- runtimeType → Type
-
