That way, I can see the images each user has uploaded

问题 After a lot of searching, I've found a lot of "what not to do" when it comes to reading firebase collections (main example being the incident of the $30k bill), however I'm struggling to find a suitable solution for our problem. Our website contains a product catalogue. The catalogue is populated from a firestore collection called 'products', with the JSON structure as: "products"{ "productId"{ "name": "price": "brand": ... } } In order to load the collection, I use the following: this

问题 I am trying to make multiple queries to Firestore and merge the results into one stream like here. I tried using StreamGroup.merge() but it's only returning the results of one stream. I noticed that it does actually get data for all the streams but only returns one when everything completes. Here is what I did: Stream getStream(){ List<Stream> streams = []; streams.add(Firestore.instance.collection(Constants.REQUESTS_NODE). where("municipality",isEqualTo: "City of Johannesburg Metropolitan").

问题 It seems odd to me that Firestore would charge me for read queries to locally cached data, but I can't find any clarification to the contrary in the Firestore Pricing document. If I force Firebase into offline mode and then perform reads on my locally cached data, am I still charged for each individual entity that I retrieve? Second, offline users in my app write many small updates to a single entity. I want the changes to persist locally each time (in case they quit the app), but I only need
