Please describe the feature you would like to request.

I'm using MatButton directive as attribute like this:
<button mat-button buttonType="{{button.type}}></button>"
I want to change 'mat-button' directive according to 'button.type', for example if 'button.type' is 'stroked' then 'mat-button' changed to 'mat-stroked-button'. How can to change type of button dynamicaly?

What is the use-case or motivation for this proposal?

Is there anything else we should know?
