I found the solution. I create FAB button to change My Location button

GoogleMap(
        mapType: MapType.hybrid,
        initialCameraPosition: _kGooglePlex,
        onMapCreated: (GoogleMapController controller) {
          _controller.complete(controller);
        },
        myLocationEnabled: true,
      ),
      floatingActionButton: FloatingActionButton.extended(
        onPressed: _currentLocation,
        label: Text('My Location'),
        icon: Icon(Icons.location_on),
      ),
    );
  }

also, set the _currentLocation method to call my location

void _currentLocation() async {
   final GoogleMapController controller = await _controller.future;
   LocationData currentLocation;
   var location = new Location();
   try {
     currentLocation = await location.getLocation();
     } on Exception {
       currentLocation = null;
       }

    controller.animateCamera(CameraUpdate.newCameraPosition(
      CameraPosition(
        bearing: 0,
        target: LatLng(currentLocation.latitude, currentLocation.longitude),
        zoom: 17.0,
      ),
    ));
  }

Use padding property of GoogleMap widget

return Stack(
  children: <Widget>[
    GoogleMap(
      onMapCreated: _onMapCreated,
      initialCameraPosition: CameraPosition(
        target: _center,
        zoom: 11.0,
      ),
      mapType: _currentMapType,
      markers: _markers,
      onCameraMove: _onCameraMove,
      myLocationEnabled: true,
      padding: EdgeInsets.only(top: 40.0,),
    ),[enter image description here][1]
  ],
);

image 1: without padding

image 2: with padding
