如何在flutter中动态地按日期排序？

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

class MyData {
  String title;
  DateTime date;

  MyData({this.title, this.date});
}

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  List<MyData> dataList = [
    MyData(title: 'Item 1', date: DateTime.parse('2022-01-15')),
    MyData(title: 'Item 2', date: DateTime.parse('2022-01-12')),
    MyData(title: 'Item 3', date: DateTime.parse('2022-01-18')),
  ];

  @override
  Widget build(BuildContext context) {
    // Sort the data list by date
    dataList.sort((a, b) => a.date.compareTo(b.date));

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Dynamic Sorting'),
        ),
        body: ListView.builder(
          itemCount: dataList.length,
          itemBuilder: (context, index) {
            MyData data = dataList[index];
            String formattedDate = DateFormat('yyyy-MM-dd').format(data.date);
            return ListTile(
              title: Text(data.title),
              subtitle: Text(formattedDate),
            );
          },
        ),
      ),
    );
  }
}
