trip_routing 0.0.10

Flutter on-device trip-routing calculator package for multiple waypoints, optimized for pedestrian navigation.

Routing Trip Planner

Flutter client-side trip-routing calculator package for multiple waypoints, optimized for pedestrian navigation. This package uses overpass api to fetch all ways inside bounding box of your waypoints and calculates an optimal route between them. A detailed polyline route containing a list of LatLng points is returned.

Getting started

Add this to your package's pubspec.yaml file:

dependencies:
  trip_routing: <lastest>

Example

final waypoints = [
    const LatLng(50.77437074991441, 6.075419266272186),
    const LatLng(50.774717242584515, 6.083980842518867),
];

final routing = TripService();
try {
    final trip = await routing.findTotalTrip(waypoints,
        preferWalkingPaths: true, replaceWaypointsWithBuildingEntrances: true);
    print('Calculated route: ${trip.route}');
    print('Distance: ${trip.distance} meters');
    print('Errors: ${trip.errors}');
} catch (e) {
    print('Error calculating route: $e');
}

findTotalTrip arguments

• waypoints: A list of LatLng objects representing the locations (latitude and longitude) between which the route needs to be calculated.
• preferWalkingPaths: Bool flag indicating whether walking paths should be preferred over other types of paths. Defaults to true.
• replaceWaypointsWithBuildingEntrances: Boolean flag that determines if waypoints should be replaced with building entrances. Defaults to false.
• forceIncludeWaypoints: Boolean flag that forces the inclusion of waypoints in the final route even if they are not exactly on a road. Defaults to false.
