        var geoFire_vendore = GeoFire(ref_vendore)
        val geoQuery =  geoFire_vendore?.queryAtLocation(GeoLocation(picklat, picklng), radius_driver)!!
        loggg("geoquery",geoQuery.toString())
        geoQuery.addGeoQueryDataEventListener(object :GeoQueryDataEventListener{
            override fun onGeoQueryReady() {
                Log.e("erropr","geoquery ready")
            }

            override fun onDataExited(dataSnapshot: DataSnapshot?) {
                Log.e("erropr",dataSnapshot.toString())
            }

            override fun onDataChanged(dataSnapshot: DataSnapshot?, location: GeoLocation?) {
                Log.e("erropr",dataSnapshot.toString())
            }

            override fun onDataEntered(dataSnapshot: DataSnapshot?, location: GeoLocation?) {
                vendorArray.put(dataSnapshot?.key?.replace("vendor",""))
                loggg("vendor list","$vendorArray")
            }

            override fun onDataMoved(dataSnapshot: DataSnapshot?, location: GeoLocation?) {
                Log.e("erropr",dataSnapshot.toString())
            }

            override fun onGeoQueryError(error: DatabaseError?) {
                Log.e("erropr",error.toString())
            }

        })
    }`

@kishanverma26 saying that it "doesn't work" is not enough information to help debug. What is happening, what do you expect to happen, do you see any errors, are you sure your data is correct, etc?
