Type Definition wrong for Child Renderer of Form.Item

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

<Form.Field shouldUpdate >
        {(form) => {
          // this is then undefined according to type definition but holds the item path to access the element!
          console.log(form.prefixName)

          // type should be from https://github.com/react-component/field-form/blob/e118381c2102b36c4ffe7e17a6415df091e772b7/src/interface.ts#L233
          
          return (
              <Form.Field name="fun" hidden={form.getFieldValue([...form.prefixName, 'other'])}>
                <Input />
              </Form.Field>
          )
        }}
      </Form.Field>

What is expected?

the type for the passed form should include the prefixName property

What is actually happening?

the prefixName property is accessible but not defined in the type

const { xxx } = React.useContext(FieldContext);

by now it is no longer possible to get the context as in https://github.com/ant-design/ant-design/issues/30529#issuecomment-850272255.

Is there any other way to do this?
