ion-back-button not showing without defaultHref

Issue

I'm using angular's own routing this.router.navigate(['/locaties']);. When I navigate forward it still doesn't show up. What am I doing wrong?

toolbar.component.html

<ion-toolbar color="primary">
  <ion-buttons slot="start">
    <ion-back-button slot="start"></ion-back-button>
  </ion-buttons>

  <ion-title> {{ _toolbarTitle | async }} </ion-title>

  <img slot="end" src="assets/specto_logo.svg" />
</ion-toolbar>

Solution

It is because there is nothing on the ionic history stack. In order to have it show you must use the ionic controller.

this.navCtrl.navigateForward('/locaties');
