AnnotationLayoutResult class

Result of AnnotationLayoutEngine.layout: the annotations currently visible, positioned on screen and de-collided, together with the field-of-view status used to compute them.

Constructors

AnnotationLayoutResult({required List<ArAnnotation> annotations, required ArStatus status, Map<String, int> rows = const {}, Map<String, List<ArAnnotation>> groups = const {}})

Properties

annotations → List<ArAnnotation>
Visible annotations, sorted by distance, with ArAnnotation.arPosition and ArAnnotation.arPositionOffset populated. arPosition is the label's top-left corner in screen coordinates, the label being centered on the POI's projection.
final
groups → Map<String, List<ArAnnotation>>
Annotations that did not fit on screen once stacked, by the ArAnnotation.uid of the visible annotation they are grouped into (the overlapping one whose label is horizontally closest). They are not part of annotations and have ArAnnotation.isVisible false.
final
hashCode → int
The hash code for this object.
no setterinherited
rows → Map<String, int>
Overlap row of each visible annotation, by ArAnnotation.uid. Pass it back as previousRows to the next AnnotationLayoutEngine.layout call to keep labels on stable rows across frames.
final
runtimeType → Type
A representation of the runtime type of the object.

status → ArStatus
