I have been trying to make my toolbar shrink after scrolling down for the last 9 hours...

I tried "scrollDispatcher" example here: Shrinkable mat-toolbar

but it tells me "Cannot find name 'map'." in:

.pipe(
map((....

I tried this (html):

<mat-sidenav-content fxFlexFill cdkScrollable>

(ts):

ngOnInit() {
   this.scrollDispatcher.scrolled()
      .subscribe(event=> console.log('you have scrolled'))
}

but also doesn't do anything when scrolling...

did angular team change that? how do I solve it?

map is an operator in rxjs6, you aren't getting any console logs? – Joshua Chan May 13 '18 at 05:14
Did you import `map`? It's now a pipeable operator and should be imported like `import { map } from 'rxjs/operators'`; – Edric May 13 '18 at 14:05
