title: How can I resize a polygon on google map using flutter?
body: <p>I'm using google_maps_flutter package to use google maps and add a polygon.I want to resize/adjust the polygon to get the correct area. </p>
  
  <p>I tried searching for any property to adjust, but did not find one.</p>
  
  <p>This is the code where I'm adding the polygon to google maps.</p>
  
  <pre><code>Widget build(BuildContext context) {
   return MaterialApp(
     home: Scaffold(
       appBar: AppBar(
         title: Text('Maps Sample App'),
         backgroundColor: Colors.green[700],
         actions: &lt;Widget&gt;[
           IconButton(
               icon: Icon(Icons.call_made),
               tooltip: 'Sign Out',
               onPressed: _signOut),
         ],
       ),
       body: Container(
         height: MediaQuery.of(context).size.height,
         width: MediaQuery.of(context).size.width,
         child: GoogleMap(
             onMapCreated: _onMapCreated,
             initialCameraPosition: CameraPosition(
               target: LatLng(widget.location.first.latitude,
                   widget.location.first.longitude),
               zoom: 11.0,
             ),
                   polygons: Set&lt;Polygon&gt;.of(&lt;Polygon&gt;[
               Polygon(
                 polygonId: PolygonId('area'),
         points: _points,
         geodesic: true,
         strokeColor: Colors.blue,
         fillColor: Colors.lightBlue.withOpacity(0.1),
         visible: true
               )
             ]),
             markers: Set&lt;Marker&gt;.of(&lt;Marker&gt;[
               Marker(
                   markerId: MarkerId('1'),
                   position: LatLng(widget.location.first.latitude,
                       widget.location.first.longitude),
                   visible: true,
                   draggable: true)
             ])),
       ),
     ),
   );
  }
