agm-direction is freezing my application or won't load. Is this a library issue?

[vikingschris]

I'm having issues with agm-direction. When I use agm-direction component inside agm-marker, my page won't load or would be stuck. I've check every for an answer before deciding to ask this question.

app.module.ts

  declarations: [
    AppComponent,
    PropertyMapComponent,
    MapWrapperComponent
  ],
  imports: [
    BrowserModule,
    AgmCoreModule.forRoot({
      apiKey: apiKey,
      libraries: ['places', 'geometry']
    }),

    AppRoutingModule
  ],

  bootstrap: [AppComponent]
})
export class AppModule { }

map.component.html

<agm-map [latitude]="destination.lat" [longitude]="destination.lng">
  <agm-marker [latitude]="destination.lat" [longitude]="destination.lng"></agm-marker>
  <agm-marker [latitude]="origin.lat" [longitude]="origin.lng"></agm-marker>
  <agm-direction [origin]="origin" [destination]="destination"></agm-direction>
</agm-map>

map.component.ts

  public get origin(): any {
    return { lat: 25.7782341, lng: -80.1867595 };
  }

  public get destination(): any {
    return { lat: 25.7616798, lng: -80.1917902 };
  }

I'm not getting any errors. The page either won't load, or would be stuck.

Try this:

ngOnInit() {
  // initial
  this.getDirection();
}

getDirection() {
  this.origin = { lat: 25.7782341, lng: -80.1867595 };
  this.destination = { lat: 25.7616798, lng: -80.1917902 };
}

Yes that was able to work. Thank you. Why do I have to assign the variable inside ngOnInit lifecycle? What happens if you want to pass the origin and destination as an Input() to a component?
