initialPayload property

dynamic initialPayload

Payload to be sent with the connection_init request.

Can be a literal value, a callback, or an async callback. End value must be valid argument for json.encode.

Internal usage is roughly:

Future<InitOperation> get initOperation async {
  if (initialPayload is Function) {
    final dynamic payload = await initialPayload();
    return InitOperation(payload);
  } else {
    return InitOperation(initialPayload);
  }
}

Implementation

final dynamic initialPayload;
