This Flutter project is a guided project inspired by Maximilian Schwarzmüller's Udemy Course: Learn Flutter & Dart to Build iOS & Android Apps.

• Apply state management using the Riverpod library.
• Capture and save favorite places with images.
• Retrieve the user's current location using GPS.
• Utilize Google Maps API to display maps and location addresses.
• Save data to the device's local storage.

The project's file structure looks like this:

favorite_places:
    assets:
        .env
    lib:
        models:
            place.dart
        providers:
            places_provider.dart
        screens:
            add_place.dart
            map.dart
            place_details.dart
            places.dart
        widgets:
            image_input.dart
            location_input.dart
            places_list.dart
        main.dart
    pubspec.yaml
    README.md

The Home Screen displays a list of favorite places that the user has saved. Users can tap on a place to view its details.

The Add Place Screen allows users to add a new favorite place. Users can enter a place name, take a picture, and select the location either manually on the map or by using the device's GPS.

The Place Details Screen displays the details of a saved place, including its name, image, address, and a map showing the location. Users can tap on the map to view it in a larger size.

The Map Screen displays a map with a marker at the user's current location. Users can also tap on the map to select a location.

Flutter Riverpod is a state management library used to manage the app's state in a modular and testable way. It was used to manage the list of favorite places. Below is an example of how it was used:

class FavoritePlacesNotifier extends StateNotifier<List<Place>> {
  FavoritePlacesNotifier() : super([]);

  // ...

  void addFavoritePlace(String name, File img, PlaceLocation location) async {
    // ...

    final db = await getDatabase();
    db.insert('user_places', {
      'id': place.id,
      'title': place.name,
      'image': place.img.path,
      'lat': place.location.latitude,
      'lng': place.location.longitude,
      'address': place.location.address,
    });
    
    state = [...state, place];
  }

  // ...
}

The image_picker package was used to capture images from the device's camera. Here's an example of its usage:

void _takePicture() async {
  final img = await ImagePicker().pickImage(
    source: ImageSource.camera,
    maxWidth: double.infinity,
    maxHeight: double.infinity,
  );

  // ...
}

The location package was used to retrieve the device's current location. Here's an example of its usage:

void getCurrentLocation() async {
  Location location = Location();

  // Check if location services are enabled and request permission if needed

  locationData = await location.getLocation();
  final lat = locationData.latitude;
  final lng = locationData.longitude;

  saveLocation(lat, lng);
}

GoogleMap(
  initialCameraPosition: CameraPosition(
    target: ...
    zoom: 16,
  ),
  onTap: ...,
  markers: {...},
)

Before you start using the project, make sure to replace the placeholder Google Maps API Key in the .env file with your own API key obtained from Google Cloud. (You can get one here.)

GOOGLE_MAPS_API_KEY='your_api_key_here'

Also, see the packages documentation to adjust your Android and iOS projects accordingly.

1. Clone this repository to your local machine:

git clone https://github.com/khayyam-ahmed/favorite_places.git

2. Create a .env file in the assets folder and add you API key.
3. Run the app on your device or emulator:

flutter pub get
flutter run

This project is based on the tutorial by Maximilian Schwarzmüller and was created as a learning exercise in Flutter, Dart, Riverpod state management and Google Cloud Console.
