flutter package for osrm client api and open source routing service

Routing Client Dart Package

Package for osm routing client api

for now this package support only server based on osrm-backend

client api support

• OSRM Client Api
  • route service
  • trip service

Installing

Add the following to your pubspec.yaml file:

dependencies:
  routing_client_dart: ^0.5.5

example for route service

List<LngLat> waypoints = [
      LngLat(lng: 13.388860, lat: 52.517037),
      LngLat(lng: 13.397634, lat: 52.529407),
      LngLat(lng: 13.428555, lat: 52.523219),
    ];
    final manager = OSRMManager();
    final road = await manager.getRoad(
      waypoints: waypoints,
      geometries: Geometries.polyline,
      steps: true,
      languageCode: "en",
    );

example for trip service

List<LngLat> waypoints = [
      LngLat(lng: 13.388860, lat: 52.517037),
      LngLat(lng: 13.397634, lat: 52.529407),
      LngLat(lng: 13.428555, lat: 52.523219),
    ];
    final manager = OSRMManager();
    final road = await manager.getTrip(
      waypoints: waypoints,
      roundTrip:false,
      source: SourceGeoPointOption.first,
      destination: DestinationGeoPointOption.last,
      geometries: Geometries.polyline,
      steps: true,
      languageCode: "en",
    );

build instruction from road

    final instructions = await manager.buildInstructions(road);

example for check Location in Road

final currentLocation = LngLat.fromList(lnglat: [13.389147, 52.527549]);
    final isOnPath =
await roadManager.isOnPath(road, currentLocation, tolerance: 5);

Example to get next navigation instruction of current Location

final currentLocation = LngLat.fromList(lnglat: [13.389147, 52.527549]);
    final isOnPath =
final instruction = await roadManager.nextInstruction(instructions, road, currentLocation, tolerance: 5);

Warning the precision of LngLat should be 5 if the road contain polylineEncoded, or the same precies as LngLat in polylines

Note you can get some inaccurate information nextInstruction,for that we will be happy for yours contributions
