import { Pipe, PipeTransform } from "@angular/core";
import { AbstractControl } from "@angular/forms";

@Pipe({
  name: "controlRequired"
})
export class ControlRequiredPipe implements PipeTransform {
  public transform(control: AbstractControl): boolean {
    //  Return when no control or a control without a validator is provided
    if (!control || !control.validator) {
      return false;
    }

    //  Return the required state of the validator
    const validator = control.validator({} as AbstractControl);
    return validator && validator.required;
  }
}
