flutter_polyline_points_mapbox 1.0.0

A flutter package to get polyline points by either passing the coordinates or mapbox encoded polyline string

flutter_polyline_points_mapbox

A flutter plugin that decodes encoded mapbox polyline string into list of geo-coordinates suitable for showing route/polyline on maps

Getting Started

This package contains functions to decode google encoded polyline string which returns a list of co-ordinates indicating route between two geographical position

Usage

To use this package, add flutter_polyline_points_mapbox as a dependency in your pubspec.yaml file.

Import the package

import 'package:flutter_polyline_points_mapbox/flutter_polyline_points_mapbox.dart';

First method

Get the list of points by Geo-coordinate, this return an instance of PolylineResult, which contains the status of the api, the errorMessage, and the list of decoded points.

PolylinePoints polylinePoints = PolylinePoints();
PolylineResult result = await polylinePoints.getRouteBetweenCoordinates(
        mapboxApiKey: mapboxApiKey,
        request: PolylineRequest(
        origin: PointLatLng(_originLatitude, _originLongitude),
        destination: PointLatLng(_destLatitude, _destLongitude),
        mode: TravelMode.driving,
        wayPoints: [PolylineWayPoint(location: "Itire/Ikate, Surulere. Lagos.")],
        ),
);
print(result.points);

Second method

Fetch polyline with alternative routes. This method returns a list of PolylineResult

List<PolylineResult> resulte = await PolylinePoints().getRouteBetweenCoordinates(
      mapboxApiKey: mapboxApiKey,
      request: PolylineRequest(
        origin: PointLatLng(_originLatitude, _originLongitude),
        destination: PointLatLng(_destLatitude, _destLongitude),
        mode: TravelMode.driving,
        wayPoints: [PolylineWayPoint(location: "Itire/Ikate, Surulere. Lagos.")],
      ),
    );
print(results.length);
