import { AbstractControl, ValidatorFn, FormGroup } from '@angular/forms';

export const validateMinMax = (minControlName: string, maxControlName: string): ValidatorFn =>
  (control: AbstractControl): { [key: string]: boolean } | null => {
    const minControl = control.get(minControlName);
    const maxControl = control.get(maxControlName);

    if (!minControl || !maxControl) {
      return null;
    }

    const minAmount = minControl.value;
    const maxAmount = maxControl.value;

    if (maxAmount !== null && minAmount !== null && (maxAmount < minAmount || minAmount > maxAmount)) {
      // Manually set error state on controls
      minControl.setErrors({ minMaxError: true });
      maxControl.setErrors({ minMaxError: true });
      return { minMaxError: true };
    }

    // Manually clear error state if no validation error
    minControl.setErrors(null);
    maxControl.setErrors(null);
    return null;
  };
