DiagramPasteHandler typedef

DiagramPasteHandler = Future<bool> Function(DiagramController controller, String? text)

Handles text pasted on a canvas that holds no copied diagram content, such as Mermaid source. Browser gestures supply their clipboard text; native keyboard requests pass null so the handler can read the clipboard. Return true when the paste was handled.

Implementation

typedef DiagramPasteHandler = Future<bool> Function(
  DiagramController controller,
  String? text,
);
