I am trying to get my route params inside a resolve. However it doesn't contain the params but when I use activatedRoute from inside a component it does work. I think it's because the route hasn't changed yet inside the resolve. How do I get this to work?

post.resolve.ts

@Injectable()
export class PostResolver implements Resolve<any> {
    slug: any;

    constructor(
        private activatedRoute: ActivatedRoute,
        private memoryService: MemoryService,
        ) {}

    resolve() {

        console.log(this.activatedRoute);

        this.activatedRoute.params.subscribe(params => {
            this.slug = params['slug'];
            console.log(this.slug);
            return this.memoryService.getPost(this.slug);
        })

    }
}

app.route.ts

{
    path: 'post/:slug',
    component: PostComponent,
    data: {title: 'Post'},
    resolve: {
        post: PostResolver
    }
},
import { Resolve, ActivatedRouteSnapshot } from '@angular/router';

resolve(route: ActivatedRouteSnapshot) {
    console.log(route.data); // {title: "Post"}
}

TypeError: Cannot read property 'params' of undefined. I can't explain why the interface Resolve requires any argument types, but to make it work just add <any> argument type to Resolve. resolve() gets 2 arguments while it's executing, but this.route tries to get the property of this class with name route, which is not correct.

resolve(route: ActivatedRouteSnapshot) {
   console.log(route.data.title); // "Post"
   console.log(route.params['slug']) // prints the dynamic parameter value
}
