如何在EditForm中访问单个字段的验证？

import React from 'react';
import { Form, Input, Button } from 'antd';

const EditForm = () => {
  const [form] = Form.useForm();

  const onFinish = (values) => {
    console.log('Success:', values);
  };

  const onFinishFailed = (errorInfo) => {
    console.log('Failed:', errorInfo);
  };

  return (
    <Form
      form={form}
      name="edit_form"
      onFinish={onFinish}
      onFinishFailed={onFinishFailed}
    >
      <Form.Item
        label="Username"
        name="username"
        rules={[
          { required: true, message: 'Please input your username!' },
          { min: 5, message: 'Username must be at least 5 characters!' },
        ]}
      >
        <Input />
      </Form.Item>

      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
      </Form.Item>
    </Form>
  );
};

export default EditForm;

const usernameField = form.getFieldInstance('username');
console.log(usernameField.validateStatus); // 输出验证状态，如 'validating', 'success', 'error'
console.log(usernameField.errors); // 输出错误信息数组
