In the ever-evolving world of mobile development, location-based services are becoming increasingly essential. If you’re looking to implement location updates in the background for both Android and iOS applications using Flutter, you’re in the right place! This guide will walk you through the process step by step, ensuring that you can seamlessly integrate background location services into your Flutter applications.

Background Overview

The Flutter plugin discussed here facilitates acquiring location updates in the background through the utilization of CoreLocation for iOS and FusedLocationProvider for Android. It’s compatible with iOS 10.0 and above.

Getting Started

• Step 1: Add the plugin to your pubspec.yaml file:

dependencies:
  background_location: ^0.13.0

• Step 2: Install the plugin from the command line:

$ flutter packages get

Alternatively, you might prefer your editor’s built-in support for running flutter packages get.

How to Use the Plugin

Now that you’ve installed the plugin, it’s time to put it to use!

1. Import the Package: Include the plugin in the Dart file where you intend to use it:

import 'package:background_location/background_location.dart';

2. Request User Permissions: You may use the permission_handler package to handle user permissions smoothly.
3. Configure Notification (Android Only): Set the notification title, message, and icon.

BackgroundLocation.setAndroidNotification(
  title: 'Notification title',
  message: 'Notification message',
  icon: '@mipmap/ic_launcher',
);

4. Set Localization Interval (Android Only): Define how often to receive location updates in milliseconds:

BackgroundLocation.setAndroidConfiguration(1000);

5. Start the Location Service: Initiate location services and ensure they stop cleanly:

BackgroundLocation.stopLocationService();
BackgroundLocation.startLocationService();

6. Handle Location Updates: Define a callback function to handle updates:

BackgroundLocation.getLocationUpdates((location) {
  print(location);
});

Understanding Location Service Logic

Imagine you’re setting up a GPS tracker for a pet. First, you need to attach a collar (this would be like setting up your Flutter app). Then, you configure how often you want to receive an update on your pet’s location (setting the interval). You tag your notifications to let you know when a location update is available (just like the notification setup) and finally, you monitor your pet using the tracker—this step corresponds to starting services and handling updates in your Flutter app. If you fail to take off the collar (like not stopping the service), you may get repeated alerts about your pet’s position unnecessarily!

Troubleshooting and Tips

• Ensure you have declared all required permissions in both your iOS and Android app.
  • iOS: Check your info.plist for keys like NSLocationAlwaysUsageDescription.
  • Android: Verify your AndroidManifest.xml includes necessary permissions for location access.
• If the location services are called multiple times, remember to stop any existing services before starting a new one with BackgroundLocation.stopLocationService();.
