saveRemember<T> method

Future<T> saveRemember<T>(String key, int seconds, dynamic callback())

Saves a value in the cache with an expiration time.

Implementation

Future<T> saveRemember<T>(
  String key,
  int seconds,
  Function() callback,
) async {
  if (_store.containsKey(key)) {
    final entry = _store[key]!;
    if (entry.expiration == null ||
        NyTime.now().isBefore(entry.expiration!)) {
      return entry.value as T;
    }
  }

  T value;
  if (callback is Future Function()) {
    value = await callback() as T;
  } else {
    value = callback() as T;
  }

  final expiration = NyTime.now().add(Duration(seconds: seconds));
  _store[key] = _CacheEntry(value: value, expiration: expiration);
  return value;
}
