Flutter Agora.io呼叫屏幕 [英] Flutter Agora.io calling screen

问题描述

我想像Messenger(Facebook)一样添加应用内(视频)通话.当一方创建频道而另一方加入频道时，该功能将起作用.

I want to add in-app (video) calling like Messenger (Facebook) does. It works when one party creates channel and another one joins.

但是有没有一种方法可以创建呼叫屏幕，使乙方可以接受或拒绝呼叫?我正在寻找Agora.io文档，但找不到适合于此的任何内容.

But is there a way to create calling screen where party B can accept or reject call? I am looking in Agora.io documentation but cannot find anything suitable for this.

这是我的代码...

 Future<void> initialize() async {
    if (APP_ID.isEmpty) {
      setState(() {
        _infoStrings.add(
          'APP_ID missing, please provide your APP_ID in settings.dart',
        );
        _infoStrings.add('Agora Engine is not starting');
      });
      return;
    }

    await _initAgoraRtcEngine();
    _addAgoraEventHandlers();
    await AgoraRtcEngine.enableWebSdkInteroperability(true);
    await AgoraRtcEngine.setParameters('''
{\"che.video.lowBitRateStreamParameter\":{\"width\":320,\"height\":180,\"frameRate\":15,\"bitRate\":140}}''');
    await AgoraRtcEngine.joinChannel(null, 'Test', null, 0);
  }

  Future<void> _initAgoraRtcEngine() async {
    AgoraRtcEngine.create(APP_ID);
    AgoraRtcEngine.enableVideo();
  }

  void _addAgoraEventHandlers() {
    AgoraRtcEngine.onError = (dynamic code) {
      setState(() {
        final info = 'onError: $code';
        _infoStrings.add(info);
      });
    };

    AgoraRtcEngine.onJoinChannelSuccess = (
      String channel,
      int uid,
      int elapsed,
    ) {
      setState(() {
        final info = 'onJoinChannel: $channel, uid: $uid';
        _infoStrings.add(info);
      });
    };

    AgoraRtcEngine.onLeaveChannel = () {
      setState(() {
        _infoStrings.add('onLeaveChannel');
        _users.clear();
      });
    };

    AgoraRtcEngine.onUserJoined = (int uid, int elapsed) {
      setState(() {
        final info = 'userJoined: $uid';
        _infoStrings.add(info);
        _users.add(uid);
      });
    };

    AgoraRtcEngine.onUserOffline = (int uid, int reason) {
      setState(() {
        final info = 'userOffline: $uid';
        _infoStrings.add(info);
        _users.remove(uid);
      });
    };

    AgoraRtcEngine.onFirstRemoteVideoFrame = (
      int uid,
      int width,
      int height,
      int elapsed,
    ) {
      setState(() {
        final info = 'firstRemoteVideo: $uid ${width}x $height';
        _infoStrings.add(info);
      });
    };
  } 

推荐答案

在这种情况下，您需要将channelId推送到其他用户移动设备.CS Guy已在您的视频管上创建了非常有用的视频，以执行此步骤以及调用屏幕.

You will need to push channelId to other user mobile in this case. The CS Guy has created very useful video on you tube to implement this step as well as calling screen.
