try this :

 import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class MapsDemo extends StatefulWidget {
  @override
  State createState() => MapsDemoState();
}

class MapsDemoState extends State {
  final Set _markers = {};

  void _onAddMarkerButtonPressed() {
    print('in _onAddMarkerButtonPressed()');
    setState(() {
      _markers.add(Marker(
        // This marker id can be anything that uniquely identifies each marker.
        markerId: MarkerId("111"),
        position: LatLng(30.666, 76.8127),
        infoWindow: InfoWindow(
          title: "bingo! This works",
        ),
        icon: BitmapDescriptor.defaultMarker,
      ));
    });
    print('setState() done');
  }

  GoogleMapController mapController;
  //Map permissions = await PermissionHandler().requestPermissions([PermissionGroup.contacts]);import 'package:permission_handler/permission_handler.dart';

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Column(
          children: [
            Container(
              height: MediaQuery.of(context).size.height,
              width: MediaQuery.of(context).size.width,
              child: GoogleMap(
                markers: _markers,
                onMapCreated: (GoogleMapController controller) {
                  mapController = controller;
                },
                initialCameraPosition:
                    CameraPosition(target: LatLng(30.666, 76.8127), zoom: 15),
              ),
            ),
          ],
        ),
        floatingActionButton: FloatingActionButton(onPressed: () {
          print('in fab()');
          double mq1 = MediaQuery.of(context).devicePixelRatio;



          _onAddMarkerButtonPressed();

          mapController.animateCamera(
            CameraUpdate.newCameraPosition(
              CameraPosition(
                target: LatLng(30.666, 76.8127),
                zoom: 15.0,
              ),
            ),
          );
        }));
  }
}
