如何一次设置所有的formik值？

import React from 'react';
import { useFormik } from 'formik';

const MyForm = () => {
  const formik = useFormik({
    initialValues: {
      firstName: '',
      lastName: '',
      email: '',
    },
    onSubmit: values => {
      console.log(values);
    },
  });

  const setAllValues = () => {
    formik.setValues({
      firstName: 'John',
      lastName: 'Doe',
      email: 'john.doe@example.com',
    });
  };

  return (
    <form onSubmit={formik.handleSubmit}>
      <input
        type="text"
        name="firstName"
        onChange={formik.handleChange}
        value={formik.values.firstName}
      />
      <input
        type="text"
        name="lastName"
        onChange={formik.handleChange}
        value={formik.values.lastName}
      />
      <input
        type="email"
        name="email"
        onChange={formik.handleChange}
        value={formik.values.email}
      />
      <button type="button" onClick={setAllValues}>
        Set All Values
      </button>
      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;
