title: Using Polyline for making custom route with google_maps_flutter plugin - Flutter
body: <p><code>google_maps_flutter</code> 0.5.6 Added support for <code>Polylines</code> on <code>GoogleMap</code>.
  But there is no code or documentation available under my view.</p>
  
  <p>A plugin named maps_view exists which supports polylines</p>
  
  <pre><code>import 'package:map_view/map_view.dart';
  import 'package:map_view/polyline.dart';
  ...
  MapView mapView = MapView();
  mapView.addPolyline(Polyline('my_polyline', [
    Location(45.52309483308097, -122.67339684069155),
    Location(45.52298442915803, -122.66339991241693),
  ]));
  </code></pre>
  
  <p>I need the same function that's built-in with <code>google_maps_flutter</code>.</p>
