longPressEvents method

Cancelable longPressEvents({
  1. required dynamic onLongPress(
    1. PointAnnotation
    ),
})

Registers long press event callbacks for the annotations managed by this manager.

Note: This event will be triggered simultaneously with the dragEvents onBegin if the annotation is draggable.

Implementation

Cancelable longPressEvents({required Function(PointAnnotation) onLongPress}) {
  return _annotationInteractionEvents(
          instanceName: "$_channelSuffix/$id/long_press")
      .cast<PointAnnotationInteractionContext>()
      .listen((data) => onLongPress(data.annotation))
      .asCancelable();
}
