FlutterError - ParallelWaitError: Instance of 'StorageException' on iOS

[PabloTortosaLopez]

I am encountering a FlutterError - ParallelWaitError: Instance of 'StorageException' when using the flutter_secure_storage package to write data. This error occurs during the SecureStorage.write operation and ONLY on iOS. I can't find the root of the problem, it seems to fail randomly.

Steps to Reproduce

1. Add flutter_secure_storage 9.2.2 version to your pubspec.yaml
2. Initialise flutter_secure_storage in your Flutter application:

final storage = FlutterSecureStorage(
              aOptions: AndroidOptions(
                encryptedSharedPreferences: true,
                resetOnError: true,
               ...
              ),
            )

3. Attempt to write data to secure storage

@override
  Future<void> write({required String key, required String value}) async {
    try {
      await storage.write(key: key, value: value);
    } catch (error, stackTrace) {
      Error.throwWithStackTrace(StorageException(error), stackTrace);
    }
  }

4. Observe the error

Fatal Exception: FlutterError
