But when i am doing auto login case, i am calling deleteAll function in secure storage, then again write function calling, it shows Error: PlatformException(Unexpected security result code, Code: -25300, Message: The specified item could not be found in the keychain., -25300, null)--
So please use deleteAll function also please.

Thanks for the great insight !

we should not return dynamic, you can use Future is better, right?

[@AIWithFlutter]

Yup, you are right. You can actually use Future.

Bro, what should I use SQLite or Hive for local storage

[@AIWithFlutter]

Hi, it depends on what data you wanted to store. SQLite stores structured data in row and column while hive store key value pairs. If both ways of storing data workable in your case, go for hive. Hive will be much faster than SQLite.
