有没有办法在flutter中只有一个DateTimePicker上的一年、一个月、一天和一小时？

dependencies:
  flutter_cupertino_date_picker: ^1.0.12

import 'package:flutter/material.dart';
import 'package:flutter_cupertino_date_picker/flutter_cupertino_date_picker.dart';

class MyDateTimePicker extends StatefulWidget {
  @override
  _MyDateTimePickerState createState() => _MyDateTimePickerState();
}

class _MyDateTimePickerState extends State<MyDateTimePicker> {
  DateTime _selectedDateTime = DateTime.now();

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        showCupertinoModalPopup(
          context: context,
          builder: (BuildContext context) {
            return Container(
              height: 200,
              child: CupertinoDatePicker(
                mode: CupertinoDatePickerMode.dateAndTime,
                initialDateTime: _selectedDateTime,
                onDateTimeChanged: (DateTime newDateTime) {
                  setState(() {
                    _selectedDateTime = newDateTime;
                  });
                },
              ),
            );
          },
        );
      },
      child: Text(
        '${_selectedDateTime.year}年 ${_selectedDateTime.month}月 ${_selectedDateTime.day}日 ${_selectedDateTime.hour}时',
        style: TextStyle(fontSize: 16),
      ),
    );
  }
}
