From fefd49c865fe4dd6ba5f3f2d1647dd04cd1f149c Mon Sep 17 00:00:00 2001 From: GRACENOBLE Date: Wed, 24 Jun 2026 19:17:33 +0300 Subject: [PATCH 1/5] feat(mobile): onboarding and Firebase authentication (closes #37) - Navigation Compose NavHost with three routes: onboarding, auth (login/register), and home; start destination is resolved by combining DataStore onboarding flag with Firebase auth state so the app routes correctly on every cold start - AuthRepository interface + FirebaseAuthRepository: signInWithEmail, registerWithEmail (creates user + sets displayName), signInWithGoogle via Credential Manager API, and signOut - AuthViewModel exposes AuthUiState (Idle / Loading / Success / Error), currentUser StateFlow, and clearError(); uses ViewModel factory pattern for manual injection (no DI framework) - AppViewModel combines authStateFlow + hasSeenOnboarding into a single StartDestination StateFlow (null while initialising); nav graph waits until resolved before showing anything - OnboardingScreen with "Get Started" CTA; completion writes to DataStore via DataStoreOnboardingRepository so it is only shown once - LoginScreen: email + password fields, Google sign-in button, error Snackbar, link to Register - RegisterScreen: name / email / password / confirm-password fields with client-side password-match guard, error Snackbar, link to Login - HomeScreen: shows displayName (falls back to email), sign-out button; displayName is derived from FirebaseUser in AppNavGraph so the screen stays logic-free - 39 unit tests (AuthViewModel, OnboardingViewModel, AppViewModel) using fake repository stubs; 18 instrumented test stubs for all screens - Dependencies added: navigation-compose 2.9.0, firebase-auth-ktx (BOM), credentials 1.5.0 + credentials-play-services-auth, googleid 1.1.1, datastore-preferences 1.1.7, lifecycle-viewmodel-compose 2.9.0 --- mobile/app/build.gradle.kts | 10 ++ .../company/template/auth/LoginScreenTest.kt | 125 ++++++++++++++
