discontinuedPackage jet_cad_floor_plan has been discontinued and replaced by jet_cad_2d_plan.

cancel method

@override void cancel(ToolContext ctx)

Every cancel path (Escape, ToolController.activate, the layer's deactivate and dispose) drops the pending shape and never touches the document (invariant 3).

Implementation

@override
void cancel(ToolContext ctx) {
  clearShape();
  // Ruling F-3: a tool that returns after a switch away paints no stale
  // snap marker; the next pointer move resolves a fresh one.
  _hoverVisible = false;
  _syncCamera(ctx);
  notifyListeners();
}
