participantRequested function

void participantRequested(ParticipantRequestedOptions options)

Handles the participant request to join the event.

This function takes a ParticipantRequestedOptions object, which contains the user's request, the current request list, waiting room list, and functions to update the request list and the total count.

Example usage:

final options = ParticipantRequestedOptions(
  userRequest: Request(id: "user123", reason: "join"),
  requestList: [Request(id: "user1", reason: "help")],
  waitingRoomList: [WaitingRoomParticipant(id: "user2", name: "Alice")],
  updateTotalReqWait: (count) => print("Total requests: $count"),
  updateRequestList: (list) => print("Updated request list: $list"),
);

participantRequested(options);
// Output:
// "Updated request list: [{ id: 'user1', reason: 'help' }, { id: 'user123', reason: 'join' }] "
// "Total requests: 3"

Implementation

void participantRequested(ParticipantRequestedOptions options) {
  // Check if a request from this participant already exists
  final existingIndex = options.requestList.indexWhere(
    (req) => req.id == options.userRequest.id,
  );

  List<Request> updatedRequestList;
  if (existingIndex != -1) {
    // Update existing request instead of adding duplicate
    updatedRequestList = List<Request>.from(options.requestList);
    updatedRequestList[existingIndex] = options.userRequest;
  } else {
    // Add the user request to the request list
    updatedRequestList = List<Request>.from(options.requestList)
      ..add(options.userRequest);
  }
  options.updateRequestList(updatedRequestList);

  // Update the total count of requests and waiting room participants
  final reqCount = updatedRequestList.length + options.waitingRoomList.length;
  options.updateTotalReqWait(reqCount);
}
