In this tutorial, you'll learn how to implement form validation in react native with Formik and Yup. Here I have shown you how to create validation schema in Yup and how to validate a password for a strong password and match it with confirm password field. Also how to validate fixed digits number input in a field.

RegEx for Strong Password ^(?=.*?[AZ])(?=.*?[az])(?=.*?[09])(?=.*?[#?!@$%^&*]).{8,}$

RegEx for Digits Only ^[09]+$
