如何在formik中根据一个字段设置另一个字段的输入值？

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

const MyForm = () => {
  const formik = useFormik({
    initialValues: {
      field1: '',
      field2: '',
    },
    onSubmit: values => {
      console.log(values);
    },
  });

  const handleField1Change = event => {
    const newValue = event.target.value;
    formik.setFieldValue('field1', newValue);
    formik.setFieldValue('field2', newValue); // 根据field1设置field2的值
  };

  return (
    <form onSubmit={formik.handleSubmit}>
      <input
        type="text"
        name="field1"
        value={formik.values.field1}
        onChange={handleField1Change}
      />
      <input
        type="text"
        name="field2"
        value={formik.values.field2}
        onChange={formik.handleChange}
      />
      <button type="submit">提交</button>
    </form>
  );
};

export default MyForm;
