Flutter url_launcher在调用时忽略数字符号(#)

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('URL Launcher'),
        ),
        body: Center(
          child: ElevatedButton(
            child: Text('Open URL'),
            onPressed: () {
              launch(Uri.encodeComponent('https://example.com/#section'));
            },
          ),
        ),
      ),
    );
  }
}
