RoutingService class abstract Routes & Navigation

Static service for asynchronous route calculation and navigation planning.

Provides methods to calculate routes between waypoints using configurable preferences, supporting multiple transport modes (car, pedestrian, bicycle, public transit, truck), route types (fastest, shortest, economic), and various routing constraints (avoid tolls, ferries, traffic, etc.). All route calculations execute asynchronously with callback-based result delivery and comprehensive error reporting.

Example

TaskHandler? taskHandler = RoutingService.calculateRoute(
  [departureLandmark, destinationLandmark],
  routePreferences,
  (err, routes) {
    if (err == GemError.success) {
      // Do something with the calculated routes
    } else {
      print('Error: $err');
    }
  },
);
