如何在react-admin中访问自定义组件中的表单数据？

import { FormDataConsumer } from 'react-admin';

const MyCustomForm = () => (
  <FormDataConsumer>
    {({ formData }) => (
      // 在这里可以访问到表单数据
      // 可以根据需要进行处理或展示
      <div>{formData.fieldName}</div>
    )}
  </FormDataConsumer>
);

import { Edit, SimpleForm, TextInput } from 'react-admin';
import MyCustomForm from './MyCustomForm';

const MyEdit = (props) => (
  <Edit {...props}>
    <SimpleForm>
      <TextInput source="fieldName" />
      <MyCustomForm />
    </SimpleForm>
  </Edit>
);
