flutter_polyline_points 0.2.1

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

flutter_polyline_points

A flutter plugin that decodes encoded google 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 as a dependency in your pubspec.yaml file.

import 'package:flutter_polyline_points/flutter_polyline_points.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);
print(result.points);

Second method

Decode an encoded google polyline string e.g _p~iF~ps|U_ulLnnqC_mqNvxq`@

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

See the example directory for a complete sample app
