A flutter plugin that decodes encoded google polyline string into list
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 the package
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 _piFps|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
