How to make initialCameraPosition from my address in flutter google maps?

Issue

I tried to determine my address’s camera position by using ‘geolocator’ library but I don’t know how to set it into the google map’s initial camera position

searchAndNavigate() {
      searchAddress = widget.author.address;
      Geolocator().placemarkFromAddress(searchAddress).then((result) {
        mapController.animateCamera(CameraUpdate.newCameraPosition(CameraPosition(
            target:
            LatLng(result[0].position.latitude, result[0].position.longitude),
            zoom: 10.0)));
      });
    }

    void onMapCreated(controller) {
      setState(() {
        mapController = controller;
      });
    }

    Widget mapSection = Container(
      height: 400,
      width: 400,
      child: Card(
        shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(12.0)),
        child: GoogleMap(
          onMapCreated: onMapCreated,
          initialCameraPosition: CameraPosition(
            target: LatLng(40.7128, -74.0060), zoom: 10.0)),
      ),
    );

    @override
    void initState() {
      super.initState();
      searchAndNavigate();
    }

Solution

This is how I set initial camera position

//initialize _center
Position _center;
final Set<Marker> _markers = {};

 @override
  void initState() {
    super.initState();
//Then define _center in initState 
    _center = Position(locationData.latitude, locationData.longitude);

 _markers.add(
      Marker(
        // This marker id can be anything that uniquely identifies each marker.
        markerId: MarkerId(_center.toString()),
        position: _center,
        infoWindow: InfoWindow(
          title: widget.hearingItem.location.locationName,
          snippet: widget.hearingItem.location.address,
        ),
        icon: BitmapDescriptor.defaultMarker,
      ),
    );
  }


 GoogleMap(
      myLocationEnabled: true,
      onMapCreated: _onMapCreated,
      markers: _markers,
      gestureRecognizers: <Factory<OneSequenceGestureRecognizer>>[
        Factory<OneSequenceGestureRecognizer>(
          () => EagerGestureRecognizer(),
        ),
      ].toSet(),
//Finally assign _center to target in CameraPosition
      initialCameraPosition: CameraPosition(
        target: _center,
        zoom: 11.0,
      ),
    );
