179-180: Verify translation accuracy for "Demo"
The English word "Demo" is used in both English and Krio versions. Consider if this needs localization to Krio or if it's an intentionally preserved English term.
✅ Verification successful
"Demo" appears to be an acceptable English term in Krio context
Looking at the codebase:
- "Demo" is used consistently in both English and Krio versions
- Several other English terms are preserved in the Krio translations where they represent technical or widely adopted concepts (e.g., "Surveys", "Overview", "In Progress")
- This follows a common localization pattern where certain technical or universally recognized terms are intentionally kept in English

I also do not get why we need the organization fetch logic now here, too?
There was a problem hiding this comment.
@KarinBerg, the organization fetch logic is included in both the authStateChanges listener and the init method to ensure that the AuthState always contains the most up-to-date organization information. This way, whether the user's authentication state changes or the app initializes, the associated organization data is fetched and emitted with the AuthState.

💡 Codebase verification
DemoManager initialization is problematic
Multiple instances of DemoManager are being created despite singleton pattern:
- Main initialization:
main.dart:final demoManager = DemoManager() - Widget initialization:
phone_input_page.dart:demoManager = DemoManager()
This breaks the singleton pattern and can lead to inconsistent demo state across the app.
🔗 Analysis chain
Verify DemoManager initialization
DemoManager is injected into multiple repositories but its initialization state isn't verified.
Also applies to: 30-30, 47-47, 56-56, 62-62, 68-68
Let me check the complete implementation and usage of DemoManager to verify its initialization pattern and potential issues.

Use dependency injection for DemoManager
Creating a new instance of DemoManager could lead to inconsistent demo state. Consider injecting it through the constructor or using a dependency injection framework.
class _PhoneInputPageState extends State<PhoneInputPage> {
late final RoundedLoadingButtonController btnController;
late final TextEditingController phoneNumberController;
late PhoneNumber number;
- late DemoManager demoManager;
+ final DemoManager demoManager;
+ _PhoneInputPageState({required this.demoManager});

void initState() {
super.initState();
btnController = RoundedLoadingButtonController();
phoneNumberController = TextEditingController();
number = PhoneNumber(isoCode: "SL");
- demoManager = DemoManager();
}Also applies to: 22-22, 30-30
There was a problem hiding this comment.
@KarinBerg, to fix this issue, you can inject the existing instance of DemoManager instead of creating a new one. Here's how you can modify your code:
-
Update the
PhoneInputPageconstructor to acceptDemoManager:class PhoneInputPage extends StatefulWidget { final DemoManager demoManager; const PhoneInputPage({super.key, required this.demoManager}); @override State<PhoneInputPage> createState() => _PhoneInputPageState(); }
-
Modify
_PhoneInputPageStateto use theDemoManagerfrom the widget:class _PhoneInputPageState extends State<PhoneInputPage> { late final RoundedLoadingButtonController btnController; late final TextEditingController phoneNumberController; late PhoneNumber number; @override void initState() { super.initState(); btnController = RoundedLoadingButtonController(); phoneNumberController = TextEditingController(); number = PhoneNumber(isoCode: "SL"); // Remove the line where you create a new instance of DemoManager // demoManager = DemoManager(); } @override Widget build(BuildContext context) { // Access DemoManager via widget.demoManager // ... } }
-
Pass the existing
DemoManagerinstance when creatingPhoneInputPage:// Wherever you instantiate PhoneInputPage PhoneInputPage(demoManager: demoManager);
Alternatively, if you're using a state management solution like Provider, you can provide DemoManager higher up in the widget tree and access it using:
final demoManager = Provider.of<DemoManager>(context);This ensures that you're using the same instance of DemoManager throughout your application and avoids inconsistent states.

AI is not right about the second instance. But I agree with the AI that injecting the DemoManage instance would be cleaner and more bullet-proofed.

Demo manager is singleton. I'm not sure we really want and can provide it properly. I hate to say that but I don't "feel" the DI in our project at all still 😄

9-10: Consider initializing data sources in constructorLate initialization could lead to runtime errors if accessed before initialization. Consider moving these initializations to the constructor.
class PaymentRepository { - late PaymentDataSource remoteDataSource = PaymentRemoteDataSource(firestore: firestore); - late PaymentDataSource demoDataSource = PaymentDemoDataSource(); + final PaymentDataSource remoteDataSource; + final PaymentDataSource demoDataSource;
20-20: Consider adding error handling for data source selectionWhile the selection logic is clean, consider adding error handling for cases where data sources might not be properly initialized.
- PaymentDataSource get _activeDataSource => demoManager.isDemoEnabled ? demoDataSource : remoteDataSource; + PaymentDataSource get _activeDataSource { + try { + return demoManager.isDemoEnabled ? demoDataSource : remoteDataSource; + } catch (e) { + throw StateError('Data source not properly initialized: $e'); + } + }
22-48: Add error handling and logging to repository methodsWhile the delegation to data sources is clean, consider adding error handling and logging for better debugging and error recovery.

Add proper stream controller disposal
While subscription cleanup is handled well, the stream controller itself should be closed when no longer needed.
Stream<User?> authStateChanges() {
final StreamController<User?> authStateController = StreamController();
StreamSubscription<User?>? authStateSubscription;
authStateSubscription = _activeDataSource.authStateChanges().listen((authState) {
authStateController.add(authState);
});
demoManager.isDemoEnabledStream.listen((isDemoMode) {
authStateSubscription?.cancel();
authStateSubscription = _activeDataSource.authStateChanges().listen((authState) {
authStateController.add(authState);
});
authStateController.onCancel = () {
authStateSubscription?.cancel();
+ authStateController.close();
};
});
return authStateController.stream;

Should we really close it? We want to maintain the controller here as it will in the end get the other (switched) authStateSubscribtion.

@MDikkii, you can indeed keep the StreamController open if you want to maintain the same stream across multiple state changes. Once you close a StreamController, it won’t accept new subscriptions or data events, which can be counterproductive if you still need to switch between demo and remote modes on the same stream.
However, it’s generally considered good practice to close the controller when it’s no longer needed (for instance, when the object or widget that owns it is disposed). So if the controller lives for the duration of the entire app session, leaving it open may be acceptable. If it’s tied to a shorter lifecycle, make sure to close it at the appropriate time to avoid potential leaks.

🛠️ Refactor suggestion
Add userId validation before Firestore update.
Validate that recipient.userId is not null before using it in the Firestore update operation.
Apply this diff:
@override
Future<void> updateRecipient(Recipient recipient) async {

+ throw ArgumentError('recipient.userId cannot be null or empty');
