import { Component } from '@angular/core';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';

@Component({
  selector: 'app-my-form',
  template: `
    <form [formGroup]="myForm">
      <input type="text" formControlName="myField">
      <button (click)="clearErrors()">Clear Errors</button>
    </form>
  `
})
export class MyFormComponent {
  myForm: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.myForm = this.formBuilder.group({
      myField: ['', Validators.required]
    });
  }

  clearErrors() {
    const myFieldControl = this.myForm.get('myField');
    myFieldControl.setErrors(null);
  }
}
