I have an Angular site with a page that uses ng2-pdf-viewer version 6.4.1, which worked ok so far for displaying a PDF file that the user selects from several options. I need the capability to hook into the loaded event though, so the app can keep track of the currently loaded file. I have this:

<pdf-viewer class="viewer" [src]="pdfViewerSource" [render-text]="false"[zoom]="pdfViewerZoomFactor" [original-size]="false" (after-load-complete)="onPdfLoaded($event)">

The event get's called but it only contains these fields that I don't know how to process:

Do I have to read the src property of the viewer to get the URL? This might lead to problems because loading takes quite some time.
