Dynamically enable and disable a angular material input field

I try to disable and enable a angular material input field in typescript. I found only solutions where the value is set on creation time or in html like

inputField = new FormControl({ value: '', disabled: this.disabled });


I tried using the disable method like

formControl.disable(true);


but this results in the error "Type 'true' has no properties in common with type '{ onlySelf?: boolean | undefined; emitEvent?: boolean | undefined; }'."

As I understood, the onlySelf information indicates if the form or only the single field should be validated, so I tried to set it as an additional parameter like:

formControl.disable( true, { onlySelf: true });


This also does not succeed. Can somebody help me with the correct syntax for dynamically enabling/disabling an input field in Angular?

Best Regards
