will help you I think you need to clear the errors before you can update the Validity. In the linked post, the answer by Julia P. covers how to clear the errors. Then you run updateValueandValidity. How can I manually set an Angular form field as invalid?

Zend_Form_Element::clearValidators() doesn't seem to be working

Hope that helps There is the possibility of having an allowEmpty flag on an element. Try:
$element = $form->getElement('field1');
$element->clearValidators();
$element->setAllowEmpty(true);
var_dump($element->isValid(''));
print_r($element->getErrors());

hop of those help? Use get method on form variable frm1. And use ngOnInit() instead of ngAfterViewInit()
ngOnInit() {  
   this.frm1.get('family').valueChanges.subscribe( x => console.log(x));
}

it should still fix some issue Errors are not cleared when validators are dynamically cleared. You need to use setErrors(null) to clear all the previous validation errors.

Angular Reactive Form - How to add subscribe valueChanges to a single control inside Form Control in Form Array

To fix this issue In Angular Reactive Forms I have form control "name" and form array control "skills", I can add valueChange subscribe to whole skills, but is there any way to add valueChange subscribe to "skillname" alone which is inside "skills". , you can use get and at functions.
this.exp.skills.at(yourindex).skillname.valueChanges.subscribe(name=>
          { //sample code });
this.exp.get('skills').at(yourIndex).get('skillname').valueChanges.subscribe(name=> {});

clearValidators() is working fine with FormControl but does not working with FormGroup

may help you . this.form.get('details').clearValidatros(), clean the validator of details, not the validators of form.get('details.control1),form.get('details.control2)...
Imagine some like
form=new FormGroup(
  {
  control:new FormControl('',Validators.required),
  control:new FormControl('',Validators.required),
  },{ validators: identityRevealedValidator })
