- Simpler API with direct store access
- Better TypeScript support with proper type inference
- Easier testing (no provider wrapper needed)
- Can be used outside React components
Testing:
- 23 comprehensive unit tests covering all functionality
- Tests for authentication flow, error handling, and edge cases
- 100% code coverage for core auth operations
Usage:
import { useAuthStore, initAuthStore } from '@/stores/authStore';
// In app/_layout.tsx
initAuthStore();
// In components
const { user, isAuthenticated, logout } = useAuthStore();
// Or use selectors for optimized re-renders
const user = useAuthUser();
const isAuthenticated = useIsAuthenticated();

Implemented proper BLE cleanup mechanism on user logout:
**Root Cause:**
- BLE cleanup callback was being set but reference could become stale
- No explicit cleanup call in profile logout handler
- Callback stability issues due to re-renders
**Changes:**
1. app/_layout.tsx:

- Set callback once with ref that always points to current cleanupBLE
- Cleanup callback on unmount to prevent memory leaks
2. app/(tabs)/profile/index.tsx:
- Add explicit cleanupBLE() call in logout handler
- Import useBLE hook to access cleanup function
- Ensure cleanup happens before logout completes
3. services/api.ts:
- Update setOnLogoutBLECleanupCallback signature to accept null
- Allows proper cleanup of callback on unmount
4. jest.setup.js:
- Add AsyncStorage mock to prevent test failures
5. Tests:
- Add comprehensive BLE cleanup tests
- Test callback pattern and stability
- Test logout flow with BLE cleanup
- Test error handling during cleanup
**Result:**

Implemented null/undefined handling throughout NavigationController
and useNavigationFlow hook to prevent crashes from invalid data:
- Added null checks for all profile and beneficiary parameters
- Validated beneficiary IDs before navigation (type and value checks)
- Added fallback routes when data is invalid or missing
- Implemented safe navigation with error handling and logging
