A flutter plugin that decodes encoded google polyline string into list of geo-coordinates suitable for showing route/polyline on maps. We have improved the accuracy for polyline points which was previously breaking up on longer routes and used to go over the building without taking major turns.


Now – Updated

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


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

Import the package

import 'package:flutter_polyline_points/flutter_polyline_points_wrapper.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(googleAPiKey,
        _originLatitude, _originLongitude, _destLatitude, _destLongitude);

Second method

Decode an encoded google polyline string e.g _piFps|U_ulLnnqC_mqNvxq`@

List<PointLatLng> result = polylinePoints.decodePolyline("_p~iF~ps|U_ulLnnqC_mqNvxq`@");

See the example directory for a complete sample app
