4 years ago I have a similar problem. I would like to access the secure storage while the app is in the background. I use the workmanager package.
Initialization:
Workmanager.initialize(callbackDispatcher, isInDebugMode: true);
The callbackDispatcher method:
void callbackDispatcher() {
Workmanager.executeTask((task, inputData) async {
switch (task) {
case Workmanager.iOSBackgroundTask:
try {
var secureStorage = FlutterSecureStorage();
String value = await secureStorage.read(key: "aKey");
Log.i("callbackDispatcher ... $value.");
} catch (e, s) {
Log.e("$e ... $s.");
}
break;
}
return Future.value(true);
});
}However, I always receive the following exception when I simulate the background fetch.
MissingPluginException(No implementation found for method read on channel plugins.it_nomads.com/flutter_secure_storage) ...

4 years ago Hi, I have installed this plugin, and I have the same issue. I tried unistalling the app, but it does not work. Is there a workaround for this issue?
thank you in advance

4 years ago For me the error also disappeared. Most probably because I cleaned everything and/or uninstalled and reinstalled the app. I don't know what could cause that error. Fortunately it works properly now.
Please note that sometimes the installed plugin version is not in sync with the pubspec.yaml file. You can check the pub-cache (for me it is ~/.pub-cache/hosted/pub.dartlang.org) folder to check what version is installed.
In pubspec.yaml:
flutter_secure_storage: ^3.3.1+1

4 years ago I just thought that it would work with MacOS if it worked with iOS turns out it doesn't so I used the dependency from this PR - https://github.com/mogol/flutter_secure_storage/pull/91 (not sure why it hasn't been merged) :
flutter_secure_storage:
git:
url: git://github.com/openresearch/flutter_secure_storage.git
ref: feature/macos_supportNow it works great.

4 years ago Everything is fine when I use 'flutter run --release' to run the app on my android device. However, if I use 'flutter build apk' to build an apk then transfer it to my android device and run it, the problem arises.
My devices are of Android 6 and Android 10
Deleted my local pub cache and regenerated it using 'flutter pub get', still no improvements.

Many thanks!
The problem disappears by using this workaround!
But I think this is not a final solution as people may still need to 'shrink code'.
And I am worrying about whether or not Google will try to shrink the uploaded appbundle automatically to re-introduce this issue.
Anyway, some progress has been made!

3 years ago After few hours of surfing. Finally SOLVED for me. Here is what I found out.
If you are calling flutter_secure_storage (or any packages) method in background service (as example, when you are using notification onBackgroundMessage). This exception occurred because usually our plugin registered at main.dart in foreground, but if we are calling our plugin's method in background we need to manually registered our plugin in our app/src/main/[kotlin/java]/.../Application.[java or kt].
Inside the Application.java or Application.kt
After done that, do flutter run again. Hope it helps!

If you are running in web-based platform, use localstorage library.

@KoheiKanagu Agreed that in 4.1.0 they don't have support for the web and macOS but is there any planning to provide support for the macOS and web in the future?

Thank you for quick response. We'll go ahead and add our own mocks.
But in future won't it be possible to add something as simple as SharedPreferences.setMockInitialValues({});.
Thank you!!!

2 years ago Firstly, I am sorry if I am mistaken to giving answer to this issue but I was getting same error for trying to write unit test for my local project. So if I am not mistaken, we can't use the secure storage directly at tests. For this reason I write a simple mixin for my mock data source. If any one needs it, you can use it.
`mixin MockSecureStorageMixin{ ///We can't use secure storage at test time with our mock class so for that reason, ///we can use this mixin with our mock class. ///class CustomMockClass with MockSecureStorageMixin ///if we will test a model with fromJson, we can do this: ///test("bla bla", (){ /// final TestModelType _testModel=....; /// mockObject.mockSetSecureStorageTestValue(key, json.encode(_testModel.toJson())); /// ///}); final Map<String, String> _mockSecureStorageValueMap={};
///You can change the test delay based on your tests. final Duration _mockSecureStorageTestDelay=const Duration(milliseconds: 50);
Future<String?> mockGetSecureStorageTestValue(dynamic key)async{ await Future.delayed(_mockSecureStorageTestDelay); return _mockSecureStorageValueMap[key.toString()]; }
Future
Future<String?> mockSecureStorageTestValue(dynamic key)async{ await Future.delayed(_mockSecureStorageTestDelay); if(_mockSecureStorageValueMap.containsKey(key.toString())){ _mockSecureStorageValueMap.remove(key.toString()); } }
