QueryreF geoflutterfire

[hacen27]

How can I perform a geospatial query using GeoFlutterFire to find nearby locations within a certain radius from a given latitude and longitude?
Exemple 👍

var queryRef = _firestore
.collection('speedtestlocation2')
.where('IPInfo', isNotEqualTo: 'Unknown ISP')
.orderBy('IPInfo')
.orderBy('avrg',
descending:
true);

  var streams = geo.collection(collectionRef: queryRef).within(
      center: center,
      radius: 10,
      field: 'position',
      strictMode:
          true);
