Trying to add a component to the DOM with ViewContainerRef createComponent. However, the component depends on NgControl. The end goal is to add components to a form using the FormBuilder.
Can't seem to wrap my head around dependency injection when it comes to NgControl.
Is there a way to set the formControlName when programmatically creating a component?
createNgControlComponent() {
// Add control to form group
this.controlName ;
this.formGroup.addControl(
this.controlName.toString(),
this.formBuilder.control('', [])
);
// Create component
// ERROR Error: NG0201: No provider for NgControl found in NodeInjector.
const componentRef = this.form.createComponent(
CustomControlValueAccessorComponent
);
// componentRef.instance.controlDir = new FormControlName();
}

We can add a mediator component that will set the formControlName. I changed your code to work with a mediator. See if this helps - https://stackblitz.com/edit/angular-ivy-fz8rgo?file=src/app/custom-control-value-accessor/cva-mediator.component.ts
