A Flutter package that allow you to access mapbox direction api into google map.
mapbox_polyline_points #
A flutter plugin that allow you to user mapbox direction api into google map
|
Getting Started #
This package contains List of List coordinates that allow you to more that one routes
Usage #
To use this package, add mapbox_polyline_points as a dependency in your pubspec.yaml file.
Import the package #
import 'package:mapbox_polyline_points/mapbox_polyline_points.dart';
method #
Get the list of points by Geo-coordinate, this return an instance of MapboxPolylineResult, which contains the status of the api, the errorMessage, and the list of decoded points.
MapboxPolylinePoints mapboxPolylinePoints = MapboxPolylinePoints();
MapboxPolylineResult result = await mapboxPolylinePoints.getRouteBetweenCoordinates(mapboxAPiKey,
_originLatitude, _originLongitude, _destLatitude, _destLongitude);
print(result.points);
