Platform Setup

iOS (Required)

1. Add permissions to Info.plist:

<key>NSLocationWhenInUseUsageDescription</key>
<string>Your location is used to track your trips.</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Your location is used even in background.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Your location is used even when the app is closed.</string>

2. Enable Background Modes in Xcode:

Open Xcode > Runner > Signing & Capabilities > + Capability > Background Modes, then enable:

• Location updates

Android (Required)

1. Add permissions to android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_LOCATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

2. Register the foreground service inside <application>:

    android:foregroundServiceType="location"
    android:exported="false" />

Usage

import 'package:background_location_plus/background_location_plus.dart';

// 1. Initialize (call once)
await BackgroundLocationPlus.initialize();

// 2. Configure (optional — defaults: best accuracy, 5s interval, 10m distance)
await BackgroundLocationPlus.configure(
  accuracy: "best",        // "best", "balanced", or "low"
  timeInterval: 5,         // seconds (iOS only — Android uses interval in ms via LocationRequest)
  distanceFilter: 10,      // meters
  notificationTitle: "Tracking",       // Android notification title
  notificationText: "Recording trip",  // Android notification body
);

// 3. Request permissions
final granted = await BackgroundLocationPlus.requestPermissions();
if (!granted) {
  await BackgroundLocationPlus.openAppSettings();
  return;
}

// 4. Listen to location stream
BackgroundLocationPlus.onLocation.listen((loc) {
  print('${loc['latitude']}, ${loc['longitude']}');
  print('accuracy: ${loc['accuracy']}, speed: ${loc['speed']}');
  print('timestamp: ${loc['timestamp']}');
});

// 5. Start / Stop
await BackgroundLocationPlus.start();
await BackgroundLocationPlus.stop();

// 6. Check status
final running = await BackgroundLocationPlus.isRunning();

// 7. Dispose when done
await BackgroundLocationPlus.dispose();
