If you plan to keep tracking while the app is in background, you need to enable the "Background Modes" capability and check these two options:

• Location updates
• Background fetch

Usage

Initialize the SDK with your API Key:

JawalConfig config = JawalConfig(
    apiKey: "YOUR_API_KEY",
    userId: "USER_UNIQUE_ID", 
    userDescription: "USER_DESCRIPTION", // Optional
    onInitResult: (InitResultEvent event) {
        if(event.isSuceessful) {
            /// SDK is initialized successfully
        } else {
            /// You can get the error message from event.error
            print(event.error);
        }
    },
);
Jawal.init(config);

USER_UNIQUE_ID: A unique ID for the user, it can be the user ID in your database USER_DESCRIPTION: A description for the user, it can be the user name

Location Permissions

You need to request the location permission from the user, the SDK provides a method to request the permission:

PermissionStatus locationStatus = await Jawal.requestLocationPermission();
if(locationStatus.isGranted){
    /// Optional: Ask for background location permission if you want to keep tracking while the app is in background
    PermissionStatus backgroundStatus = await Jawal.requestBackgroundLocationPermission();
}else if(locationStatus.isPermanentlyDenied) {
    /// Permission is permanently denied, you can ask the user to go to the settings and enable the permission
}

Start Tracking

Jawal.startTracking();

Stop Tracking

Jawal.stopTracking();

Listen to Location Updates

Jawal.onLocationChange((LocationChangeEvent event) {
    ///Do something with the location
});
