App Flow

1. App launches and initializes Firebase, storage, and notifications.
2. Splash screen checks onboarding, login state, and email verification.
3. User is routed to:
   • Onboarding on first launch
   • Login if signed out
   • Email verification if account is not verified
   • Home dashboard if authenticated and verified
4. Home dashboard provides:
   • Tasks
   • Profile
   • Leaderboard
   • Settings

Notification Behavior

How task reminders work

• Notifications are initialized during app startup.
• Reminder scheduling is timezone-aware.
• A task reminder is scheduled only if:
  • the global notification toggle is enabled
  • the task has a valid future reminder
  • the task is not completed
• Completing or deleting a task cancels its scheduled notifications.

Android battery saver / battery optimization

Battery optimization can delay or suppress notifications on some Android devices.

The app now includes a Battery Optimization entry in Settings:

• it reads the current optimization exemption status
• it opens the Android system battery optimization screen
• it helps the user whitelist the app for better notification reliability

Important:

• this setting cannot be silently changed by Flutter alone
• Android requires the user to confirm the change in system UI

Installation

Prerequisites

• Flutter SDK
• Firebase project configured for Android/iOS
• firebase_options.dart
• google-services.json and/or GoogleService-Info.plist

Run locally

git clone https://github.com/ArpitAswal/TaskTracker.git
cd TaskTracker
flutter pub get
flutter run

Tech Stack

• Flutter
• Provider
• Firebase Auth
• Cloud Firestore
• Hive
• SharedPreferences
• Flutter Secure Storage
• flutter_local_notifications
• timezone

Important Notes

• Android 13+ requires notification permission.
• Some Android versions/devices also require exact alarm approval for precise scheduling.
• Even with exact scheduling, aggressive OEM battery optimization may still delay alerts.
• The app provides a battery optimization settings shortcut, but the final permission change is system-controlled.
• The repository still contains a default sample widget test that does not reflect the real app bootstrap and will fail without Firebase-aware test setup.
