[Angular google-maps ]：有没有办法从typescript代码内部改变<agm-marker>属性？

<agm-marker [latitude]="markerPosition.lat" [longitude]="markerPosition.lng"></agm-marker>

export class MyComponent {
  markerPosition = { lat: 51.5074, lng: -0.1278 };

  changeMarkerPosition() {
    this.markerPosition = { lat: 40.7128, lng: -74.0060 };
  }
}

<agm-marker #marker [latitude]="51.5074" [longitude]="-0.1278"></agm-marker>

export class MyComponent implements AfterViewInit {
  @ViewChild('marker') marker: AgmMarker;

  ngAfterViewInit() {
    this.marker.latitude = 40.7128;
    this.marker.longitude = -74.0060;
  }
}

<agm-marker [latitude]="markerLatitude" [longitude]="markerLongitude"></agm-marker>

export class ChildComponent {
  @Input() markerLatitude: number;
  @Input() markerLongitude: number;
}

<child-component [markerLatitude]="51.5074" [markerLongitude]="-0.1278"></child-component>

export class ParentComponent {
  markerLatitude = 40.7128;
  markerLongitude = -74.0060;

  changeMarkerPosition() {
    this.markerLatitude = 37.7749;
    this.markerLongitude = -122.4194;
  }
}
