Media Events - Flutter

VideoSDK offers various events that can be monitored to obtain information about the media status of participants in the meeting.

Here are the events specifically related to the stream:

Events.streamEnabled

• This event is triggered whenever a participant's video, audio or screen share stream is enabled.
• It can be subscribed to using the Participant object.

Events.streamDisabled

• This event is triggered whenever a participant's video, audio or screen share stream is disabled.
• It can be subscribed to using the Participant object.

Events.streamPause

• This event is triggered whenever a participant's video, audio or screen share stream is paused.
• It can be subscribed to using the Participant object.

Events.streamResumed

• This event is triggered whenever a participant's video, audio or screen share stream is resumed.
• It can be subscribed to using the Participant object.

Example

Here is an example demonstrating the usage of all the events mentioned on this page.

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

class ParticipantTile extends StatefulWidget {
  final Participant participant;
  //Existing congiguration
}

class _ParticipantTileState extends State<ParticipantTile> {
  @override
  void initState() {
    //Existing congiguration

    setupParticipantEventListener();
  }

  @override
  Widget build(BuildContext context) {
    return YourParticipantTileWidget();
  }

  void setupParticipantEventListener() {
    widget.participant.on(Events.streamEnabled, (Stream stream) {
      if (stream.kind == "video") {
        // Participant turned on video
      } else if (stream.kind == "audio") {
        // Participant turned on audio
      } else if (stream.kind == "share") {
        // Participant started screenshare
      }
    });

    widget.participant.on(Events.streamDisabled, (Stream stream) {
      if (stream.kind == "video") {
        // Participant turned off video
      } else if (stream.kind == "audio") {
        // Participant turned off audio
      } else if (stream.kind == "share") {
        // Participant stopped screenshare
      }
    });

    widget.participant.on(Events.streamPaused, (Stream stream) {
      if (stream.kind == "video") {
        // Participant video pause
      } else if (stream.kind == "audio") {
        // Participant audio pause
      } else if (stream.kind == "share") {
        // Participant screenshare paused
      }
    });

    widget.participant.on(Events.streamResumed, (Stream stream) {
      if (stream.kind == "video") {
        // Participant video resume
      } else if (stream.kind == "audio") {
        // Participant audio resume
      } else if (stream.kind == "share") {
        // Participant screenshare resumed
      }
    });
  }
}
