OutlinerListView class

Core outliner list widget without any app-specific UI chrome.

Displays a hierarchical list of editable blocks with drag-and-drop support. All UI states (loading, error, empty) are customizable via builder callbacks.

Example basic usage:

OutlinerListView()

Example with custom styling and builders:

OutlinerListView(
  config: OutlinerConfig(
    blockStyle: BlockStyle(indentWidth: 32.0),
  ),
  loadingBuilder: (context) => MyCustomLoadingWidget(),
  emptyBuilder: (context, onAddBlock) => MyEmptyState(onAdd: onAddBlock),
)
