Issue when using limit(1) about geoflutterfire HOT 8 OPEN

Do u think u can make a query that increases range automatically to get 1 doc? so like if radius is set to 10, it will query at 2km, 4km, 6km, 8km, 10km. And if at 2km there is an item, it will stop the query there. if there is none it will increase radius till 10. Because currently its impossible to use limit(1) because like the case i stated above, if there is an item at the corner of the geo hash box, but its not in the radius, it wont return anything because its in the box but out of radius.

Hey @momoDragon this library doesn't support limit() and sortBy(), in case you use limit() it'll run limit on all 9 queries individually. This was discussed on other threads as well. I'll keep the docs updated, sorry about that!

This should give you a better explanation.

Whats the best way to make a query like uber where we only get one document back in a 10km radius when there are multiple docs present ?

There's no way to set a hard limit in this library as explained in #21, the best alternative would be to set limit(1) on your query, which would read 1 doc from all geohashes, giving you 9 reads.

So even if i dont get anything back it will charge me 9 reads?

Hey @momoDragon! I believe yes, you'll be charged at least once per query even if you don't get back any results as mentioned in the cloud_firestore docs - https://firebase.google.com/docs/firestore/pricing#minimum-charge

@momoDragon to access the doc in the neighboring geohash box and not inside radius you can set the strictMode to false! And the requirement you stated can be done using RxDart operators on the application side itself.
