Flutter Agora.io 调用屏幕

Question

我想像 Messenger (Facebook) 那样添加应用内(视频)调用。当一方创建 channel 而另一方加入时，它起作用。

但是有没有办法创建通话屏幕，让 B 方可以接听或拒绝来电？我正在查看 Agora.io 文档，但找不到任何适合于此的内容。

虽然这是我的代码...

 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);
      });
    };
  }

在这种情况下，您需要将 channelId 推送到其他用户移动设备。
CS Guy 在 You Tube 上创建了非常有用的视频来实现这一步以及调用屏幕。
