void emit<T extends EventType>(T event) {
  event.sanityCheck();
  List<dynamic>? targets = listeners[event.runtimeType];

  if (targets != null) {
    // avoid concurrent modification
    List<dynamic> copy = List<dynamic>.from(targets);

    for (dynamic target in copy) {
      try {
        //   logger.w("invoking $event on $target");
        target(event);
      } catch (e, s) {
        logger.e(e.toString(), null, s);
      }
    }
