Subject: [PATCH] Variable type does not match

This is the "original" code
final key = await secureStorage.read(key: 'key');
final encryptionKey = base64Url.decode(key!);
print('Encryption key: $encryptionKey');
final encryptedBox= await Hive.openBox('vaultBox', encryptionCipher: HiveAesCipher(encryptionKey));
 1- the variable encryptionKey is declared as final on top, so it could not be final
 2- the variable encryptionKey is typed as String? so it does not match with the return of .decode() -> Uint8List
 3- because of these, the example code does not work
I propose this :
encryptionKey = await secureStorage.read(key: 'key');
  final key = base64Url.decode(encryptionKey!);
  print('Encryption key: $key');
  final encryptedBox= await Hive.openBox('vaultBox', encryptionCipher: HiveAesCipher(key));
