是否可以在编译时获取dart/flutter项目的当前时间？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    DateTime currentTime = DateTime.now();
    String formattedTime = currentTime.toString();

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Current Time'),
        ),
        body: Center(
          child: Text(
            'Current Time: $formattedTime',
            style: TextStyle(fontSize: 24),
          ),
        ),
      ),
    );
  }
}
