Features

• Weather based on the device's GPS location
• City search and interactive map selection
• Current conditions, hourly forecast, and seven-day forecast
• Email/password and Google authentication with Firebase
• Favorite locations synchronized through Cloud Firestore
• Local weather cache for faster startup and offline fallback

Download

Download the latest Android APK from the GitHub Releases page.

Android might ask for permission to install apps from your browser or file manager because the APK is distributed outside Google Play.

Technology

• Flutter
• Firebase Authentication
• Cloud Firestore
• Open-Meteo for weather and geocoding data
• OpenStreetMap for map tiles
• Nominatim for reverse geocoding

Run Locally

Install Flutter and connect an Android device or start an emulator. Then run:

flutter pub get
flutter run

Check the project before building:

flutter analyze

Firebase Setup

The application uses Firebase Authentication and Cloud Firestore. When using your own Firebase project:

1. Register Android and iOS applications in Firebase.
2. Enable Email/Password and Google authentication.
3. Create a Cloud Firestore database.
4. Run flutterfire configure.
5. Add the Android debug and release SHA-1/SHA-256 fingerprints.
6. Deploy the rules from firestore.rules.

Firebase client configuration files contain public app identifiers. Never commit service-account credentials, signing keys, key.properties, or .env files containing secrets.

Build an Android Release

A local Android signing key and android/key.properties are required:

flutter build apk --release

The generated APK is available at:

build/app/outputs/flutter-apk/app-release.apk

Permissions

WeatherApp requests location access to show weather for the user's current position. If location access is unavailable, the app uses cached weather data or Bucharest as a fallback.
