📝 Walkthrough

Walkthrough

The changes introduce a new settings screen with logout functionality, refine authentication navigation flows (clearing the stack after login, adjusting post-registration redirects), extend error handling for email confirmation scenarios, improve profile data management in auth_helper, and add input validation to the focus viewmodel's settings and progress calculations.

Changes

Cohort / File(s)	Summary
Auth Navigation src/lib/features/auth/presentation/view/login_view.dart, src/lib/features/auth/presentation/view/register_view.dart	Modified post-authentication navigation: login now clears the stack to the first route using popUntil, and register pops back to previous route instead of pushing a new LoginView.
Settings Screen src/lib/features/main/view/screens/settings_screen.dart, src/lib/features/main/view/screens/main_screen.dart	Added new SettingsScreen widget with logout button; integrated into main screen to replace placeholder text.
Auth Error Handling src/lib/features/auth/presentation/viewmodels/auth_viewmodels.dart	Extended error translation map to recognize "email not confirmed" backend error and return localized Vietnamese message.
Profile Data Management src/lib/features/auth/services/auth_helper.dart	Refactored login and register methods: improved profile upsert logic to handle userMetadata extraction, added guard for email confirmation flow (session == null), and optimized .upsert() usage patterns.
Focus Validation src/lib/features/note/viewmodel/focus_viewmodel.dart	Added defensive guards in progress computation (prevents division by invalid totalTime) and input validation in updateSettings (ensures timer durations are at least 1 minute).

Poem

🐰 A rabbit hops through settings new,
With logout buttons shiny blue,
Auth flows cleared with popUntil care,
Validation guards prevent despair,
No more crashes—progress guarded there! 🎉
