Firestore or Provider giving back old data flutter

I am using cloud_firestore and riverpod in my project.
I have a firestore database with some data. If I delete the data in firestore, I would expected my app to notice that as well. But at first I get the old data.

@riverpod
Option<MyObject> closeObjectLocation(CloseObjectLocationRef ref) {
  final objects = ref.watch(objectsWithinRadiusProvider
      .select((value) => value.valueOrNull));

  debugPrint("objects count: ${objects?.length}");

}

The logs looks as follows:

objects count: null
objects count: 1
objects count: 0

It leads to wrong behaviours within the app.

There many layers between the provider and firestore.

@riverpod
Stream<List<Object>> objectsWithinRadius(ObjectsWithinRadiusRef 
ref) {
  final myLocation =
  ref.watch(positionStreamProvider.select((value) => 
    value.valueOrNull));
  final objectsStream = ref
  .watch(objectsWithinRadiusRepoProvider(
  myLocation!.latitude, myLocation.longitude))
  .getObjects();

  return objectsStream;
}

Here the firestore stream.

Stream<List<DocumentSnapshot>> collectionStreamWithRadius({
required String path,
required double radius,
required String field,
required GeoFirePoint center,
  }) {
    return _streamErrorHandler(
      () {
        var reference = geoFlutterFire
            .collection(collectionRef: 
        firebaseFirestore.collection(path))
        .within(
          center: center,
          radius: radius,
          field: field,
          strictMode: true,
        );

    return reference;
  },
 );
}

Basically I want to invalidate the cache when I close the app such that it fetches new values gain and not the cache one.
