flutter - DateTime.now()与我的本地时间不同

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Local Time'),
        ),
        body: Center(
          child: FutureBuilder<String>(
            future: FlutterNativeTimezone.getLocalTimezone(),
            builder: (context, snapshot) {
              if (snapshot.hasData) {
                final String timezone = snapshot.data;
                final DateTime now = DateTime.now();
                final DateFormat formatter = DateFormat('yyyy-MM-dd HH:mm:ss');
                final String formattedTime = formatter.format(now.toLocal());

                return Text(
                  'Local Time: $formattedTime\nTimezone: $timezone',
                  style: TextStyle(fontSize: 20),
                );
              } else if (snapshot.hasError) {
                return Text('Error: ${snapshot.error}');
              } else {
                return CircularProgressIndicator();
              }
            },
          ),
        ),
      ),
    );
  }
}
