    const validationSchema = yup.object({
        name: yup.string().required('Please enter name').min(2, "Name too short")
    });

    const [name, setName] = useState<string>("");

    const formik = useFormik({
        initialValues: {name},
        enableReinitialize: true,
        validationSchema: validationSchema,
        onSubmit: (values, formikHelpers) => {

        },
    });

  return (
    <div>
        <h1>Hello {name} </h1>
        <form onSubmit={formik.handleSubmit}>

Use input with mask

import { useFormik } from 'formik';
import { FormikMuiMaskedTextField, FormikMuiTextField } from 'js-mui-formik'
import { BR_MOBILE_MASK, BR_PHONE_MASK } from 'js-mui-formik'
import { useState } from 'react';
import styled from 'styled-components';
import * as yup from 'yup';

const InputWrapper = styled.div`margin: 1rem 0`;

class User {
  name: string;
  phone: string;
  mobile: string;

  constructor() {
    this.name = "";
    this.phone = "";
    this.mobile = "";
  }
}

export default function ShowInputs() {

  const validationSchema = yup.object({
    name: yup.string().required('Please enter name').min(2, "Name too short"),
    phone: yup.string().required('Please enter phone').min(11, "Phone too short"),
    mobile: yup.string().required('Please enter mobile').min(12, "Phone too short")

  });

  const [user, setUser] = useState<User>(new User);

  const formik = useFormik({
    initialValues: { ...user },
    enableReinitialize: true,
    validationSchema: validationSchema,
    validateOnMount: true,
    onSubmit: (values, formikHelpers) => {
      setUser(() => values);
      formikHelpers.resetForm();
    },
  });

  return (
    <div>
      <h1>
        Hello {user?.name ? user?.name : '______'},&nbsp;
        your phone is {user?.phone ? user?.phone : '_____'}&nbsp;
        and your mobile is {user?.mobile ? user?.mobile : '_____'}.
