Error Events - Flutter

VideoSDK provides the error event which informs you about any error happening during the meeting.

Events.error

• This event is triggered whenever an invalid configuration is provided or server/network errors arise. In such cases, the event will trigger with a specific error code and message.
• It is particularly useful for development-level troubleshooting during SDK integration.
• It can be subscribed to using the Room object.

Example

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

import 'dart:developer';

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

class MeetingScreen extends StatefulWidget {
  //Existing configuration
}

class _MeetingScreenState extends State<MeetingScreen> {
  late Room room;

  @override
  void initState() {
    //Existing configuration

    setupRoomEventListener();
  }

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

  void setupRoomEventListener() {
    room.on(Events.error, (error) {
      log("VIDEOSDK ERROR :: ${error['code']}  :: ${error['name']} :: ${error['message']}");
    });
  }
}
