Geofence_service breaks local notifications on iOS about geofence_service

[Dev-hwang]

There seems to be a feature conflict when using the singleton object UNUserNotificationCenter.current() concurrently on the iOS platform. This can be temporarily resolved as follows. I'll let you know when the problem is resolved.

  @override
  Widget build(BuildContext context) {
    Widget child = Scaffold(
      appBar: AppBar(
        title: const Text('Plugin example app'),
      ),
      body: Container(),
    );

    if (Platform.isAndroid) {
      child = WillStartForegroundTask(
        onWillStart: () async {
          // You can add a foreground task start condition.
          return _geofenceService.isRunningService;
        },
        androidNotificationOptions: const AndroidNotificationOptions(
          channelId: 'geofence_service_notification_channel',
          channelName: 'Geofence Service Notification',
          channelDescription: 'This notification appears when the geofence service is running in the background.',
          channelImportance: NotificationChannelImportance.LOW,
          priority: NotificationPriority.LOW,
          isSticky: false,
        ),
        // iosNotificationOptions: const IOSNotificationOptions(),
        notificationTitle: 'Geofence Service is running',
        notificationText: 'Tap to return to the app',
        child: child,
      );
    }

    return MaterialApp(home: child);
  }

Unfortunately the temporary solution isn't quite fitting for the project my team is working on as the geofence service is more or less an essential part of the app, along with the notifications.

So I would like to ask, is this an issue you would be looking to resolve in the short term? (and if so, would it be possible to know the estimated time? )

In version 3.4.6, this issues has been fixed.

1. Upgrade dependencies.

dependencies:
  geofence_service: ^3.4.6

2. To display a notification when your app enters the background, you need to open the ios/Runner/AppDelegate file and set the following:

Objective-C:

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GeneratedPluginRegistrant registerWithRegistry:self];

  // here
  if (@available(iOS 10.0, *)) {
    [UNUserNotificationCenter currentNotificationCenter].delegate = (id<UNUserNotificationCenterDelegate>) self;
  }

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

@end

Swift:

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)

    // here
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

If the problem persists despite upgrading the plugin, please create a new issue.
