Setting info-window offset for agm snazzy-info-window

Indeed, offset property according to angular-google-maps repository is not exposed via AgmSnazzyInfoWindow component. One option to circumvent this limitation would be to introduce a custom component which extends AgmSnazzyInfoWindow component and supports to specify offset property, for example:

import {
  Component,
  AfterViewInit,
  Input
} from "@angular/core";
import { AgmSnazzyInfoWindow } from "@agm/snazzy-info-window";

@Component({
  // tslint:disable-next-line:component-selector
  selector: 'my-info-window',
  template:
    "<div #outerWrapper><div #viewContainer></div></div><ng-content></ng-content>"
})
export class MyInfoWindowComponent extends AgmSnazzyInfoWindow
  implements AfterViewInit {

   /**
   * A custom padding size around the content of the info window.
   */
  @Input() offset: {top: string, left: string};

  ngAfterViewInit() {
    super.ngAfterViewInit();
    this._snazzyInfoWindowInitialized.then(() => {
      this._nativeSnazzyInfoWindow._opts.offset = this.offset;
    });
  }
}

Now offset could be specified like this:

<agm-map [latitude]="center.lat" [longitude]="center.lng">
  <agm-marker [latitude]="center.lat" [longitude]="center.lng">
    <my-info-window
      [offset]="{
        top: '-60px',
        left: '0px'
      }"
    >
      <ng-template>
        Phoenix
      </ng-template>
    </my-info-window>
  </agm-marker>
</agm-map>
