Added support for multiple/alternate routes, update dependencies

[aaqibismail]

Added an extra parameter, alternatives, from Google Maps API Docs for receiving multiple routes. Solves #61, #63

Adds models for bounds, legs, status_codes, and geocoded_waypoints from the json response received from the API. Updated avoid parameter according to Google Maps Documentation. Added function to parse json body to use for server-side API calls that return the json data. Supports both coordinate or place_id for origin and destination.

    }

in the inner loop result.points.first.forEach() forEach is not defined, at mouse hover showing this

The method 'forEach' isn't defined for the type 'PointLatLng'.
Try correcting the name to the name of an existing method, or defining a method named 'forEach'.dart[undefined_method](https://dart.dev/diagnostics/undefined_method)

Isn't there any example code to share with me please.

I think you’re looking at the wrong example. Look in example/lib/main.dart

if (result.routes[0].points.isNotEmpty) {
       result.routes[0].points.forEach((PointLatLng point) {
         polylineCoordinates.add(LatLng(point.latitude, point.longitude));
       });

Dear @aaqibism The getter 'routes' isn't defined for the type 'PolylineResult' This is my function which drawing polyline, is there anything I'm doing wrong?

  _getPolyline(lat1, lng1, lat2, lng2) async {
    PolylineResult result = await polylinePoints
        .getRouteBetweenCoordinates(
      mapKey,
      PointLatLng(lat1, lng1),
      PointLatLng(lat2, lng2),
      travelMode: TravelMode.driving,
    )
        .catchError((onError) {
      showSnackbar(context, "An Error Occured Possibly due to network issues");
    });
    print(result.routes); 
    if (result.points.isNotEmpty) {
      polylineCoordinates = [];
      result.points.forEach((PointLatLng point) {
        polylineCoordinates.add(LatLng(point.latitude, point.longitude));
      });
    }
    _addPolyLine();
  }
  _addPolyLine() {
    PolylineId id = PolylineId("Poly");
    Polyline polyline = Polyline(
      polylineId: id,
      width: 4,
      startCap: Cap.roundCap,
      endCap: Cap.buttCap,
      color: Colors.blue,
      points: polylineCoordinates,
    );
    polylines[id] = polyline;
  }

when I print(result.routes) routes is not defined for result, It seems you have not merged yet because in example/lib/main.dart the code looks like this

_getPolyline() async {
    PolylineResult result = await polylinePoints.getRouteBetweenCoordinates(
        googleAPiKey,
        PointLatLng(_originLatitude, _originLongitude),
        PointLatLng(_destLatitude, _destLongitude),
        travelMode: TravelMode.driving,
        wayPoints: [PolylineWayPoint(location: "Sabo, Yaba Lagos Nigeria")]);
    if (result.points.isNotEmpty) {
      result.points.forEach((PointLatLng point) {
        polylineCoordinates.add(LatLng(point.latitude, point.longitude));
      });
    }
    _addPolyLine();
  }

Dear Aqib, can you merge polyline support changes to the branch we can access.

Thanks

I’m not the owner of the repo, I don’t know how to otherwise.

Dear @Dammyololade, would you be able to do something about it?
