getAll method

@override Future<Map<String, CacheItem>> getAll(List<String> keys)

Retrieves multiple CacheItems associated with the given keys.

Returns a map where the keys are the original keys and the values are the retrieved CacheItems. If a key is not found in the cache, it will not be included in the returned map.

Throws a CacheException if there is an error retrieving the data.

Implementation

@override
Future<Map<String, CacheItem<dynamic>>> getAll(List<String> keys) async {
  if (!_isInitialized) await init();

  final result = <String, CacheItem<dynamic>>{};

  // Hive doesn't have a native getAll method, so we need to get each key individually
  // but we can optimize by doing it in a single transaction
  for (final key in keys) {
    if (_box.containsKey(key)) {
      final dynamic storedValue = _box.get(key);

      if (storedValue == null) continue;

      if (enableEncryption) {
        final decryptedValue = _decrypt(storedValue);
        result[key] = CacheItem.fromJson(jsonDecode(decryptedValue));
      } else {
        result[key] = storedValue as CacheItem<dynamic>;
      }
    }
  }

  return result;
