import 'package:jitsi_meet/jitsi_meet.dart';

void main() {
  // 初始化Jitsi Meet
  JitsiMeet.initialize();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Jitsi Meet Demo',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  void initState() {
    super.initState();
    // 加入Jitsi Meet会议
    _joinMeeting();
  }

  void _joinMeeting() async {
    try {
      // 配置Jitsi Meet会议参数
      var options = JitsiMeetingOptions()
        ..room = "your_meeting_room_id"
        ..serverURL = "https://your_jitsi_meet_server_url.com"

        ..audioOnly = true
        ..audioMuted = true
        ..videoMuted = true;

      // 加入会议
      await JitsiMeet.joinMeeting(options);
    } catch (error) {
      // 处理错误
      print("Error joining meeting: $error");
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Jitsi Meet Demo'),
      ),
      body: Center(
