treeController property

TreeController<SecKey<K>, SecPayload<Section, Item>> get treeController

Underlying tree controller. Exposed for the widget's render layer (it must construct a SliverTree against this). Not part of the supported public API for end users — calling structural methods directly on the underlying tree bypasses the section/item type invariants this controller enforces.

Implementation

TreeController<SecKey<K>, SecPayload<Section, Item>> get treeController {
  return _tree;
}
