diagramLineGeometry function
Interaction consumes the same shaped artifact as the canonical scene. A renderer must never independently reflow an unshaped resolved line.
Implementation
DiagramTextLineGeometry diagramLineGeometry(ResolvedTextLine line) =>
line.geometry ??
(throw StateError(
'Text has no shaped line geometry. Configure the store resolver with '
'FlutterDiagramTextLayoutEngine before mounting the Flutter canvas.',
));
