Implementation

@override
Future<CacheItem<dynamic>?> get(String key) async {
  final db = await database;
  final result = await db.query('cache', where: 'key = ?', whereArgs: [key]);
  if (result.isEmpty) {
    return null;
  }
  final item = result.first;
  dynamic value = item['value'];
  if (enableEncryption) {
    final decryptedValue = _decrypt(value);
    value = jsonDecode(decryptedValue);
  }
  return CacheItem<dynamic>(
    value: value,
    expiry: item['expiry'] != null
        ? DateTime.fromMillisecondsSinceEpoch(item['expiry'] as int)
        : null,
  );
}
