react-final-form中有没有函数可以获取表单值

import { useForm } from 'react-final-form';

const MyForm = () => {
  const form = useForm();

  const handleSubmit = (values) => {
    // 处理表单提交
    console.log(values);
  };

  const handleButtonClick = () => {
    const formValues = form.getState().values;
    console.log(formValues);
  };

  return (
    <form onSubmit={handleSubmit}>
      {/* 表单字段 */}
      <input name="firstName" type="text" />
      <input name="lastName" type="text" />

      <button type="submit">提交</button>
      <button type="button" onClick={handleButtonClick}>获取表单值</button>
    </form>
  );
};
