FAQ

Is this a full functional app?

No. DWallet is a UI Kit designed for developers. It contains:

• Complete visual interface
• Local state management
• Mock data for demonstration
• Full source code

You need to connect it to your own backend API (e.g., Firebase, Supabase, Laravel, Node.js) to make it fully functional with real data persistence and user accounts.

What Flutter version is required?

DWallet requires Flutter SDK ^3.10.4 or later. Ensure you have a compatible Dart SDK version as well.

Can I use this for a commercial project?

Yes, if you purchased a valid license from CodeCanyon. Please refer to the specific license terms included with your purchase.

How do I change the app name?

1. Update pubspec.yaml:

   name: your_app_name
   description: Your app description

2. Update Android app name in android/app/src/main/AndroidManifest.xml

3. Update iOS app name in ios/Runner/Info.plist

How do I add a new language?

DWallet uses the slang package for internationalization. See the Localization guide for detailed instructions on adding new languages.

Can I remove the app lock feature?

Yes, you can disable the app lock feature:

1. Go to Settings > App Lock Security
2. Turn off “Enable App Lock”

Or remove the lock screen overlay from main.dart if you don’t need it at all.

How do I change the default currency?

Users can change currency during onboarding or later in settings. To change the default for new users:

Edit packages/dwallet_types/lib/src/mocks/_user.dart:

static User guest() => UserModel(
  currency: CurrencyMock.eur, // Change default
  // ...
);

Can I add more color schemes?

Yes! DWallet supports 13 built-in color schemes. To add more:

1. Open lib/app/core/theme/_app_theme.dart
2. Add your color to the AppColorScheme enum
3. Add the color definition in _schemeColors map

See Theming & Branding for details.

How do I connect to a real backend?

You’ll need to:

1. Create API service classes in lib/app/di/services/
2. Update models to include API fields
3. Replace mock data with API calls
4. Add authentication flow (login/register)

See Authentication for backend integration guidance.

Is the data encrypted?

Currently, data is stored in SharedPreferences as plaintext. For production use with sensitive financial data, you should:

1. Use flutter_secure_storage for sensitive data
2. Encrypt data before storage
3. Implement proper backend security

Can I use this with Firebase?

Yes! DWallet can be easily integrated with Firebase:

• Firestore: Store transactions and wallets
• Firebase Auth: User authentication
• Cloud Functions: Business logic
• Analytics: Track user behavior

How do I build for release?

Android

flutter build apk --release

Or for app bundle:

flutter build appbundle --release

iOS

flutter build ios --release

Then archive and distribute through Xcode.

The lock screen is not showing

1. Ensure you’ve set a PIN in settings
2. Check that “Enable App Lock” is turned on
3. Verify AppLockLifecycleObserver is wrapping your app in main.dart
4. On Android, ensure MainActivity extends FlutterFragmentActivity

Biometric authentication is not working

1. Check device has biometric hardware
2. Ensure biometrics are enrolled in device settings
3. Verify android:enableOnBackInvokedCallback="true" in manifest
4. Check local_auth plugin is properly configured

How do I customize the charts?

DWallet uses custom painted charts. To customize:

1. Open lib/app/pages/client/analytics/components/
2. Modify _line_chart.dart or _pi_chart.dart
3. Adjust colors, labels, and animations

Can I add more wallet types?

Yes! Edit the WalletType enum in packages/dwallet_types/lib/src/abstractions/_enums.dart:

enum WalletType {
  cash,
  bank,
  mobileMoney,
  other,
  crypto, // Add new type
}

Then update the wallet creation UI to support the new type.

How do I disable the onboarding?

To skip onboarding for development:

// In AuthUserService
@override
Future<User> build() async {
  return UserModel(
    // ...
    hasCompletedOnboarding: true, // Skip onboarding
  );
}

The app crashes on startup

1. Run flutter clean
2. Delete pubspec.lock
3. Run flutter pub get
4. Ensure all dependencies are compatible
5. Check Flutter doctor: flutter doctor -v
