To trigger an action when a remote participant leaves a room or call in LiveKit, you can use the following methods depending on your programming language: • Swift: Implement the

room(_:participantDidDisconnect:)

method from the

RoomDelegate

protocol:

func room(_ room: Room, participantDidDisconnect participant: RemoteParticipant) {
    // Your action when a participant leaves
}

• Python: Register an event handler for the

participant_disconnected

event:

def on_participant_disconnected(participant):
    print(f"Participant disconnected: {participant.identity}")
    # Your action when a participant leaves

room.on("participant_disconnected", on_participant_disconnected)

• Flutter: Listen for the

ParticipantDisconnectedEvent

emitted by the

Room

class when a

RemoteParticipant

leaves the room:

// Listen for the event and implement your action when a participant leaves
