geocodedWaypoints property
Details about the geocoding of every waypoint, as well as origin and destination, can be found in the (JSON) geocoded_waypoints array. These can be used to infer why the service would return unexpected or no routes.
Elements in the geocoded_waypoints array correspond, by their zero-based position, to the origin, the waypoints in the order they are specified, and the destination.
Implementation
final List<GeocodedWaypoint>? geocodedWaypoints;
