      value = mapper(value);
    }
    add(key, [value as ContextualResource<T, C>]);
  } else if (value is Iterable) {
    for (var e in value) {
      if (mapper != null) {
        e = mapper(e);
      }
      addDynamic(key, e);
    }
  } else if (value is Function) {
    var v = value(key);
    if (mapper != null) {
      v = mapper(v);
