169-174: Add logging for authentication flowThe removal of logging makes it harder to debug authentication issues in production.
Consider adding strategic log points:
if (snapshot.connectionState == ConnectionState.done) { if (!snapshot.hasData) { + logInfo('No authentication token found, redirecting to welcome screen'); return WelcomeScreen(); } else { + logInfo('Authentication token found, proceeding to main navigation'); return NavPage(); } }
| if (snapshot.connectionState == ConnectionState.done) { | ||
| if (!snapshot.hasData) { | ||
| return WelcomeScreen(); | ||
| } else { | ||
| return NavPage(); | ||

Consider adding token validation before navigation
The simplified authentication flow might expose security vulnerabilities. Currently, any non-null token value will trigger navigation to NavPage without validation.
Consider adding basic token validation:
if (snapshot.connectionState == ConnectionState.done) {
if (!snapshot.hasData) {
return WelcomeScreen();
} else {
+ final token = snapshot.data!;
+ if (!isJwtValid(token)) {
+ HiveRepository.deleteData('token', HiveBoxNames.authBox);
+ return WelcomeScreen();
+ }
return NavPage();
}
}Add this helper function:
bool isJwtValid(String token) {
try {
final parts = token.split('.');
if (parts.length != 3) return false;
final payload = json.decode(
utf8.decode(base64Url.decode(base64Url.normalize(parts[1])))
);
final expiry = DateTime.fromMillisecondsSinceEpoch(payload['exp'] * 1000);
return DateTime.now().isBefore(expiry);
} catch (e) {
return false;
}

| logInfo('Authentication token found. Navigating to NavPage'); | ||
| return NavPage(); | ||
| return Scaffold(body: Center(child: Text('An Error occured.'))); |

🛠️ Refactor suggestion
Enhance error handling for better user experience
The generic error message provides little context to users and no recovery options.
Consider implementing a more informative error screen:
-return Scaffold(body: Center(child: Text('An Error occured.')));
+return Scaffold(
+ body: Center(
+ child: Column(
+ mainAxisAlignment: MainAxisAlignment.center,
+ children: [
+ Text(
+ 'Unable to verify your session',
+ style: Theme.of(context).textTheme.titleLarge,
+ ),
+ const SizedBox(height: 16),
+ ElevatedButton(
+ onPressed: () => setState(() {}),
+ child: Text('Retry'),
+ ),
+ TextButton(
+ onPressed: () {
+ HiveRepository.deleteData('token', HiveBoxNames.authBox);
+ Navigator.of(context).pushReplacement(
+ MaterialPageRoute(builder: (_) => WelcomeScreen()),
+ );
+ },
+ child: Text('Return to Login'),
+ ),
+ ],
+ ),
+ ),
+);Committable suggestion skipped: line range outside the PR's diff.
