FlatNode<T> class

A flattened representation of a tree node for virtualized rendering.

Contains all information needed to render a single row in a flat ListView, including depth, position flags, and ancestor "isLast" info for tree lines.

Constructors

FlatNode({required Node<T> node, required int depth, required bool isFirst, required bool isLast, required bool isRoot, required List<bool> ancestorIsLastFlags})
const

Properties

ancestorIsLastFlags → List<bool>
For each ancestor depth level, whether that ancestor is the last child. Used to decide whether to draw a vertical continuation line at that depth. Index 0 = depth 0 ancestor, index 1 = depth 1 ancestor, etc.

final
hashCode → int
