Custom event

Stream Video also supports custom events. This is a real-time layer that you can broadcast your own events to.

Sending custom events

You can use the sendCustomEvent method of the Call instance to send custom events:

call.sendCustomEvent(
    eventType: 'my-custom-event',
    custom: {
      'key': 'value',
    },
);

Receiving custom events

You can listen to custom events by listening to the StreamCallCustomEvent event via the same callEvents stream:

call.callEvents.on<StreamCallCustomEvent>((event) { });
