Can't get GoogleMap object

Issue description Hi, I am trying to create an OverlayView in order to add customized markers, such as done in this example. To do that I need to get the actual map instance. In the docs I see this should be possible with GoogleMapsAPIWrapper.getNativeMap(). However, when I try this, the Promise never returns.

Steps to reproduce and a minimal demo of the problem See example here. Where the code: this.mapsAPIWrapper.getNativeMap().then((map) => { console.log(‘Got map!’) console.log(map); }); Never returns from getNativeMap() call.

_Use https://plnkr.co or similar – try this template as a starting point: http://plnkr.co/edit/YX7W20?p=preview

What steps should we try in your demo to see the problem?

Current behavior Not returning from function call - Promise not resolved.

Expected/desired behavior Promise resolved - returning map instance.

angular2 & angular-google-maps version agm/core": “^1.0.0-beta.2” Angular 5.

Based on @agborkowski example:

HTML:

<agm-map (mapReady)="mapReady($event)"></agm-map>

TS:

mapReady(map) {
    var marker = new google.maps.Marker({
        position: {lat:40.706130, lng: -74.076870},
        map: map,
        title: 'Hello World!'
    });
}
