Access mat-raised-button disabled attribute

i try to access (read) the disabled attribute of a mat-raised-button Button inside of a directive.

If disabled is set true, inside my directive, during ngOnInit, disabled is still false, but the material button is rendered as disabled (grey).

Button:

<button
  my-directive
  mat-raised-button
  [disabled]="isDisabledOrNot()" // returns true
  (click)="doSomething()>bla</button>

My Diective @HostBinding Attempt:

export class myDirective implements OnInit {
  constructor(private element: ElementRef, private renderer: Renderer2) {}

  @HostBinding('disabled')
  disabled: any;

  ngOnInit(): void {
    console.log(`disabled:`, this.disabled); // prints false

I tried using the nativeElement:

export class myDirective implements OnInit {
  constructor(private element: ElementRef, private renderer: Renderer2) {}

  ngOnInit(): void {
    console.log(`disabled:`, this.element.nativeElement.disabled); // prints false

And i used some hack version involved class.mat-button-disabled from github issues but neither works.

I can set the disabled button using the Renderer2 setAttribute method. But that doesn't work for reading.

Any Ideas?

Inside your directive you can Inject MatButton class and check whether it is disabled or not

constructor(private button:MatButton){}
  
ngOnInit(){
    console.log(this.button.disabled);
}
