Hi there, i have an app in which i am using google map its working fine but having little problem… its fixed on lat,lng provided by me… its not moving,zooming nothing
please help …

here is the code snippet

loadMap(){
    let mapOptions: GoogleMapOptions = {
      camera: {
        target: {
          lat: 43.0741904,
          lng: -89.3809802
        },
        zoom: 18,
        tilt: 30
      }
    };

    this.map = GoogleMaps.create('map', mapOptions);

    // Wait the MAP_READY before using any methods.
    this.map.one(GoogleMapsEvent.MAP_READY)
      .then(() => {
        console.log('Map is ready!');

        // Now you can use all methods safely.
        this.map.addMarker({
            title: 'Ionic',
            icon: 'green',
            animation: 'DROP',
            position: {
              lat: 43.0741904,
              lng: -89.3809802
            },
            
          })
          .then(marker => {
            marker.on(GoogleMapsEvent.MARKER_CLICK)
              .subscribe(() => {
                alert('clicked');
              });
          });

      });
  }

Do you mean you can not control the map by any gesture?
If so, please share your project files on github. I will check it.
