How to pass form control error messages from component to child component that implements ControlValueAccessor in Angular?

Question

For now I am using @Input() to pass error messages from parent to child component that implements ControlValueAccessor. I would like to know is there better way of passing error messages. Please guide me. Thank you

<mat-form-field class="increment"> <input matInput [formControl]="_control.control" type="text" [disabled]="disabled" [max]="max" [min]="min" [errorMessage]="errorMessage" [(ngModel)]="value"/> </mat-form-field>

Let me know if you know how it can be done
