const MyApp({Key? key}) : super(key: key);

Widget build(BuildContext context) {
return const MaterialApp(
title: 'Flutter Google Maps Demo',
home: MapSample(),
class MapSample extends StatefulWidget {
const MapSample({Key? key}) : super(key: key);
State<MapSample> createState() => MapSampleState();
class MapSampleState extends State<MapSample> {
final Completer<GoogleMapController> _controller = Completer();
static const CameraPosition _london = CameraPosition(
target: LatLng(51.5071943, -0.102977),
zoom: 15,
MapType _currentMapType = MapType.normal;
void _onMapType() {
setState(() {
_currentMapType = _currentMapType == MapType.normal ? MapType.satellite : MapType.normal;
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Google Map Sample'),
body: Stack(
children: [
mapType: _currentMapType,
initialCameraPosition: _london,
onMapCreated: (GoogleMapController controller) {
padding: const EdgeInsets.all(18),
