AbstractGeometryItem class Routes & Navigation

Geometry element used by AbstractGeometry.

An AbstractGeometryItem represents a single drawable element attached to an anchor (for example a lane, arrow or waypoint marker). It contains rendering hints such as arrow presence/direction, the slot indexes where the shape attaches to the anchor, the shape form/type and any traffic restriction metadata.

Consumers typically use the TurnDetails.abstractGeometryImg property to obtain a ready-to-render image of the entire geometry.

See also:

• AbstractGeometry.items — List of geometry items attached to the anchor.

Constructors

AbstractGeometryItem({ArrowType arrowType = ArrowType.none, ArrowDirection beginArrowDirection = ArrowDirection.none, int beginSlot = -1, ArrowDirection endArrowDirection = ArrowDirection.none, int endSlot = -1, RestrictionType restrictionType = RestrictionType.none, ShapeForm shapeForm = ShapeForm.line, ShapeType shapeType = ShapeType.street, int slotAllocation = 0})

Creates an AbstractGeometryItem instance.

AbstractGeometryItem.fromJson(Map<String, dynamic> json)

Deserializes a JSON-compatible map to create an instance.
