Guys I need some help figuring out something about async storage.
on android it has a 6mb limit, I want to know what is its each key value pair limits for each key how big can be the value?

For Android, SQLite is used, so SQLite limits are appropriate. There's also an Android OS limitation on how big the data can be while reading from the DB (CursorWindow limitation) and that's around 2MB. I'm yet to find out why 6MB is a limit on Android, but I from what I've been testing, it can handle more than that (like normal SQLite). Maybe it was related to different storage used back when AsyncStorage used RockDB under the hood? You can increase this limit by following instructions here.
