@override
void addEntries(Iterable<MapEntry<K, V>> newEntries) {
  bool needNotify = false;
  for (var entry in newEntries) {
    if (!needNotify &&
        (!peek.containsKey(entry.key) || peek[entry.key] != entry.value)) {
      needNotify = true;
    }
    peek[entry.key] = entry.value;
  }

  if (needNotify) {
    notify(true);
