geofence_foreground_service 1.0.1

A Flutter project that creates a foreground service to handle geofencing.

geofence_foreground_service

A Flutter plugin that enables you to easily handle geofencing events in your Flutter app by creating a foreground service.

Features

• Geofence a circular area 🗺️: You can add a an ordinary geofence which is a point surrounded by a given radius.
• Geofence a polygon 🤯: You can add a geofence using a list of coordinates, the system will calculate the center of them and register it, having full polygon support is a WIP 🚧
• Notification customization 🔔: Displaying a notification when running a foreground service is mandatory, we can customize what is being displayed on it (title and content), the plugin displays the app icon by default.

Installation

Add the following dependency to your pubspec.yaml file:

geofence_foreground_service: ^1.0.0

Setup

🔧 Android Setup

• Enable MultiDex, you can check how to do so here
• Add the service to the

<service android:name="com.f2fk.geofence_foreground_service.GeofenceForegroundService" />

Example

import 'package:geofence_foreground_service/exports.dart';
import 'package:geofence_foreground_service/geofence_foreground_service.dart';
import 'package:geofence_foreground_service/models/zone.dart';

// This method is a top level method
@pragma('vm:entry-point')
void callbackDispatcher() async {
  GeofenceForegroundService().handleTrigger(
    backgroundTriggerHandler: (zoneID, triggerType) {
      log(zoneID, name: 'zoneID');
      log('$triggerType', name: 'triggerType');

      return Future.value(true);
    },
  );
}

  // ...
  
  // In your widget
  final GeofenceForegroundService _geofenceForegroundServicePlugin = GeofenceForegroundService();

  final List<LatLng> timesSquarePolygon = [
    const LatLng(40.758078, -73.985640),
    const LatLng(40.757983, -73.985417),
    const LatLng(40.757881, -73.985493),
    const LatLng(40.757956, -73.985688),
  ];
  
  Future<void> initPlatformState() async {
    // Remember to handle permissions before initiating the plugin

    bool hasServiceStarted = await _geofenceForegroundServicePlugin.startGeofencingService(
      contentTitle: 'Test app is running in the background',
      contentText: 'Test app will be running to ensure seamless integration with ops team',
      notificationChannelId: 'com.app.geofencing_notifications_channel',
      serviceId: 525600,
      callbackDispatcher: callbackDispatcher,
    );

    if (hasServiceStarted) {
      await _geofenceForegroundServicePlugin.addGeofenceZone(
        zone: Zone(
          id: 'zone#1_id',
          radius: 10000,
          coordinates: timesSquarePolygon,
        ),
      );
    }

    log(hasServiceStarted.toString(), name: 'hasServiceStarted');
  }

Notes

Handling permissions is not a part of the package, so please refer to permission_handler plugin to grat the required permissions (it's used in the example too)
