  final LatLng _point2 = LatLng(12.948767, 77.689120);

  @override
  Widget build(BuildContext context) {
    _polylines.add(
        Polyline(
            polylineId: PolylineId("line 1"),

      body: GoogleMap(
        // Configure google maps widget are required

        polylines: _polylines, // Add constructed polyline for curved line
        .
        .
