monitoredNodeIds property
The set of node IDs that this annotation monitors for position/size changes.
When monitorNodes is true, the annotation controller sets up MobX
reactions to watch these specific node IDs. Override to return the
nodes your annotation cares about.
Returns an empty set by default. GroupAnnotation returns its nodeIds for explicit and parent behaviors.
Implementation
@override
Set<String> get monitoredNodeIds =>
behavior != GroupBehavior.bounds ? _nodeIds.toSet() : const {};
