Running this code

Stream<List<Data>> streamListByLocation(Position currentPosition) {
    final geoPoint =
        GeoFirePoint(currentPosition.latitude, currentPosition.longitude);

    Query ref = _db
        .collection("data")
        .where("isActive", isEqualTo: true);

    return _geo
        .collection(collectionRef: ref)
        .within(center: geoPoint, field: "point", radius: 150, strictMode: true)
        .map((docs) => docs.map((doc) => Data.fromFirestore(doc)).toList());
  }

Throws the following exceptions

It's weird because it always worked until now, Versions => 0.13.1+1 for cloud_firestore and 2.0.3+8 for geoflutterfire.

Also, for additional information, here's my flutter doctor -v output
