<input
formControlName="name"
id="name"
type="text"
class="form-control">
<div *ngIf="f.name.touched && f.name.invalid" class="alert alert-danger">
<div *ngIf="f.name.errors && f.name.errors.required">Name is required.</div>
<div *ngIf="f.name.errors && f.name.errors.minlength">Name should be 3 character.</div>
</div>
</div>

<div *ngIf="f['name'].touched && f['name'].invalid" class="alert alert-danger">
<div *ngIf="f['name'].errors && f['name'].errors['required']">Name is required.</div>
