class SecureStorage {
// Create storage
late FlutterSecureStorage _storage;

static final SecureStorage _instance = SecureStorage._internal();

factory SecureStorage() {
return _instance;
}

SecureStorage._internal() {
_storage = FlutterSecureStorage();
}

// Read value
Future isSet({required String key}) async {
var val = await _storage.containsKey(key: key);
return val;
}

// Read value
Future readSecureData({required String key}) async {
var readData = await _storage.read(key: key);
return readData;
}

// Read all values
Future readAllSecureData() async {
Map<String, String> allValues = await _storage.readAll();
return allValues;
}

// Write value
Future writeSecureData({required String key, required String value}) async {
var writeData =
await _storage.write(key: key, value: value);
return writeData;
}

// Delete value
Future deleteSecureData({required String key}) async {
var deleteData = await _storage.delete(key: key);
return deleteData;
}

// Delete value
Future deleteAllSecureData() async {
var deleteData = await _storage.deleteAll();
return deleteData;
}

I am updated secure storage v9.0.0 to v9.2.2, then again same issue:
I got this Error after app close and reopen:

PlatformException(Unexpected security result code, Code: -25300, Message: The specified item could not be found in the keychain., -25300, null)--

Please any one have solution for this.

Every time i am calling the Login API for token update, and deleting all Secure Stotage data, then again saving fresh data in secure storage.

So when ever reopen the application in IOS app,
When ever try to save data in secure storage below error occurred
How to solve this.

Same here, is there a size limit?

my code:

class LocalStorageServiceSecureImpl {
  late final FlutterSecureStorage _storage;

  LocalStorageServiceSecureImpl() {
    _storage = FlutterSecureStorage(
      iOptions: _getIOSOptions,
      aOptions: _getAndroidOptions,
    );
  }

  AndroidOptions get _getAndroidOptions =>
      const AndroidOptions(encryptedSharedPreferences: true);

  IOSOptions get _getIOSOptions => const IOSOptions(
        accessibility: KeychainAccessibility.first_unlock,
        synchronizable: true,
      );

  Future<void> saveData(String key, String data) async {
    await _storage.write(
      key: key,
      value: data,
      iOptions: _getIOSOptions,
      aOptions: _getAndroidOptions,
    );
  }

  Future<String?> loadData(String key) async {
    return await _storage.read(
      key: key,
      iOptions: _getIOSOptions,
      aOptions: _getAndroidOptions,
    );
  }
}

It is a flutter_secure_storage library issue, Just replace with flutter_keychain library. https://pub.dev/packages/flutter_keychain Its similar functionality. I am using it. Its working as expected. Get Outlook for Android<https://aka.ms/AAb9ysg>

I have the same problem.

[kieranmccwayleadr]

We have this issue along with the BadPaddingException: #541 I feel we need to personally remove the Flutter Secure Storage. It's causing weird issues. Might look into flutter_keychain @sureshprokraya what has been your experience so far using this package across android and ios?

value is always null

[sureshprokraya]

As of now I don't have any issue while using flutter_keychain. Get Outlook for Android<https://aka.ms/AAb9ysg>
