Which database should I use?
I am building an app that will be monitoring crypto prices and I have most of it all figured out except this one part of the design. I am doing a callout to binance every 30 seconds and storing the ~ 63 coin prices into their own tables which will later be used by users for graphing purposes. The data stored will just be the symbol, price, and datetime which I estimate is ~30 bytes of data let row. The callout happening every 30 seconds is 2880 callouts per day and 181k rows being written to the db per day. With that being said firebase firestone would cost me $131 per year in writes alone. I think I am leaning towards firebase realtime db since reads and writes don't matter and it's just about the size of download which would just be when a user wants to graph the points, it downloads that coins table.I am building this for myself but am gonna release it to others so I'm not sure how many users there will actually be. So starting out, I want to do this for $0 of possible since it could theoretically only be me that uses it.What other db options are there that would fit my use case here? I looked into aws dynamo db and determined (if I calculated correctly) that my writes would require 126 wcus which would result in something like $500 yearly. There will be other data stored as well but this will be the bulk of it.Thanks for the feedback, really trying to pick the right solution the first time!

Flutter app’s state in Isolate
There are many ways to manage state in Flutter, but most of them are built in such a way that all the logic is executed in the main isolate of your application. Execution of network requests, working with WebSocket, potentially heavy synchronous operations (like local search), all this, as a rule, is implemented in the main isolate. This article shows other doors as well.

Flutter + Square + Fireabase
Working on a Flutter project. Still fairly new to the framework but making some good headway. Trying to use Square as the back-end for payments.Has anyone seen this done successfully?I've searched tons of tutorials and posts but none seem to cover everything fully. The all leave the "back-end" up in the air...no examples or directions on how to complete it fully.For those that know (and care), I'm able to generate a nonce.....I just have no idea what to do with it now.Side note, currently i'm using Realtime Database in Firebase. Not sure if I would need to switch over to Firestore. I assume that would require a re-arch of my entire project.
