startAnnotationResize method

void startAnnotationResize(String annotationId, ResizeHandle handle)

Starts a resize operation for any resizable annotation.

Works with any annotation that has Annotation.isResizable set to true, including GroupAnnotation and StickyAnnotation.

Implementation

void startAnnotationResize(String annotationId, ResizeHandle handle) {
  final annotation = _annotations[annotationId];
  if (annotation == null || !annotation.isResizable) return;

  runInAction(() {
    _resizingAnnotationId.value = annotationId;
    _resizeHandle.value = handle;
    _resizeStartPosition = annotation.position;
    _resizeStartSize = annotation.size;

    // Disable panning during resize
    _parentController.interaction.panEnabled.value = false;

    // Set cursor override to lock cursor during resize
    _parentController.interaction.setCursorOverride(handle.cursor);
  });
}
