I have a reactive form in Angular like below:

this.AddCustomerForm = this.formBuilder.group({
    Firstname: ['', Validators.required],
    Lastname: ['', Validators.required],
    Email: ['', Validators.required, Validators.pattern(this.EMAIL_REGEX)],
    Picture: [''],
    Username: ['', Validators.required],
    Password: ['', Validators.required],
    Address: ['', Validators.required],
    Postcode: ['', Validators.required],
    City: ['', Validators.required],
    Country: ['', Validators.required]
});

createCustomer(currentCustomer: Customer) 
{
    if (!this.AddCustomerForm.valid)
    {
        //some app logic
    }
}

this.AddCustomerForm.valid returns false, but everything looks good.

I have tried to find with checking the status property in the controls collection. But I wonder if there is a way to find the invalid ones and display to the user?
