ngOnInit

 ngOnInit() {

    this.employeeForm = this.fb.group({
      fullName: ['', [Validators.required, Validators.minLength(2), Validators.maxLength(10)]],
      contactPreference: ['email'],

Hi AbhiRam I Update your code here is link for Here

In Form Group Update this like

email: ['', [Validators.required, emailError, emailDomainError]],

Function Code change like this *

*
 * emailDomainValidations
 * @param control 
 */

function emailDomainError(control: AbstractControl): { [key: string]: any } | null {
  const email: string = control.value;
  if (email && email.indexOf("@") != -1) {
    let [_, domain] = email.split("@");
    if (domain !== "karvy.com") {
      return {
        "emailDomainError": true,
       // "email": false
      };
    }

    else {
      return null;
    }
  }
}
function emailError(control: AbstractControl): { [key: string]: any } | null {
  const email: string = control.value;

  if( email.length <3 && email.length >=1){
    return { "email" : true}
