See the results of flutter pub upgrade:

Because every version of geo_firestore depends on cloud_firestore ^0.12.2 and your app depends on cloud_firestore ^0.13.4+2, geo_firestore is forbidden.

So, because nothing_new depends on geo_firestore ^0.0.1, version solving failed.
pub upgrade failed (1; So, because nothing_new depends on geo_firestore ^0.0.1, version solving failed.)

Looking at examples, the collection is being queried by location criteria alone.
Is it possible to query near by geopoint along with some other criteria on another field?

My goal is to have a map that shows filtered markers from geo firestore, and the same filtered results in listview tiles below the map. I've gotten the markers on the map working perfectly.

populateClients() async {
Position position = await Geolocator().getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
final queryLocation = GeoPoint(position.latitude, position.longitude);
List documents = await geoFirestore.getAtLocation(queryLocation, 10.0);
documents.forEach((document) {
print(document.data);
});

The second part "listview" is what I'm having trouble with. Here is what i've tried:

• streambuilder - populates listview with snapshot unfiltered data, does not work with .for each
• .tolist - does not contruct data in proper format for a list view
• create listview from clients or markers - only shows the first geoHash, many times (.length)
• only able to list geoHash, not title

Here is my submit code:

() async {
Position position = await Geolocator().getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
await geoFirestore.setLocation((roomnameController.text), GeoPoint(position.latitude, position.longitude));

• only two fields are passed, geoHash, and location(lat,lng)
  • it seems additional fields (from a form) cannot be passed using setLocation.

My next step is to try an inheritable widget but I feel like i'm going to have the same issues, but they will be available everywhere.

Am I approaching this wrong? Did I use geofirestore correctly? Any help is appreciated.

The documentation says that removeLocation() only needs a 'documentID' parameter. However, the actual code requires a second parameter of 'location'. Looking at the code, it doesn't appear the 'location' parameter is being used. Could it be removed to match the documentation?

I've tried the following code, but it's failing to retrieve any snapshots. Using the node.js library works fine with the same center coordinates and same Firestore collection.

Working (node.js):

export const getNear = async (center: number[], radius: number) => {
  const geofirestore: GeoFirestore = new GeoFirestore(firestore);
  const geocollection: GeoCollectionReference = geofirestore.collection(
    "businesses"
  );
  const query: GeoQuery = geocollection.near({
    center: new admin.firestore.GeoPoint(center[0], center[1]),
    radius
  });
  const queryResults = await query.get();
  console.log(queryResults.docs);
  return queryResults.docs.map(doc => doc.data());
};

const getNearResponse = await business.getNear(
  [-1.7970149, -80.757148],
  1000
);

Not working (Dart):

  _populateBusinesses() async {
    final GeoFirestore geocollection =
        GeoFirestore(firestore.collection('businesses'));
    final queryLocation = GeoPoint(-1.7970149, -80.757148);
    List<DocumentSnapshot> snapshots =
        await geocollection.getAtLocation(queryLocation, 1000);
    // snapshots is always an empty List
    final documents = snapshots.map((doc) {
      return doc.data;
    }).toList();
    setState(() {
      _documents = documents;
    });
  }

I managed to trace the calls into this lib, and it seems the issue is occurring in queriesAtLocation(). Specifically in this series of calls:

    queries.add(queryForGeoHash(geoHash, queryBits)); // queries.single: GeoHashQuery
    queries.add(queryForGeoHash(geoHashE, queryBits)); // queries.single: GeoHashQuery
    queries.add(queryForGeoHash(geoHashW, queryBits)); // queries.single: GeoHashQuery
    queries.add(queryForGeoHash(geoHashN, queryBits)); // queries.single: Unhandled exception: Bad state: Too many elements
    // After this things seem broken
    queries.add(queryForGeoHash(geoHashNE, queryBits));
    queries.add(queryForGeoHash(geoHashNW, queryBits));
    queries.add(queryForGeoHash(geoHashS, queryBits));
    queries.add(queryForGeoHash(geoHashSE, queryBits));
    queries.add(queryForGeoHash(geoHashSW, queryBits));
