flutter_secure_storage | A Flutter plugin to store data in secure storage | Plugin library

I've been working on trying to build a login page with Flutter/Dart and BLoC. So far I've got a login page with two input fields for a username and password and a login button that is built off of rounded_loading_button.dart.

On first pressing the login button with nothing in either field, the appropriate error is returned in the snackbar and the button is reset.

However, the problem I'm having is that if you press the button a second time, the button continues to spin and the snackbar never shows again. It's as if there is no state being returned somehow.

I've stepped through the code, tried to reset the state but I've not found a solution. I've provided all the files below that I'm working with.

Setting LoginUserState.failed seems to only work once in this case and I can't seem to figure out how to reset it so a second attempt will show the snackbar again and any error and also reset the login button.

I have a Flutter app with a log in page. When I run the app in debug mode, the log in page is rendered properly when the app is opened. But when I build a apk release of the app with flutter build apk --release, install it and then open the app in the emulator, the login page is not rendered properly. See screenshots below.

I am using flutter to write an app, now I want to use secure storage to store the username/passowrd like this:

what is difference between this two storage option?

https://pub.dev/packages/flutter_secure_storage

https://pub.dev/packages/get_storage

This two libraries based on the same or different implementation? If I have root on smartphone I can read data from application files saved using this storage? Which library is better/more safe?

I'm going crazy because I'm trying to solve this from 3 days ago :) any one can please help me. Note: the app is already on google play, now I'm working on version 2 of app.

I'm trying to add Facebook Authentication to an existing flutter app, i was add the package to pubspec.yaml file, and doing all configuration from official docs. now when trying to debug its show error :

I am writing a flutter application where the user can essentially create notes. I have written code to create a private key for the user, which is later used to encrypt their data. The encrypted data is stored in Firebase Firestore. When their data is retrieved it is decrypted using their key.

I've looked at using Flutter Secure Storage, which works great, except that the secret key is only available on that device. If the user logs in on a new device, they will not be able to decrypt their notes.

My question is:

How/where can I store the user's secret key for decrypting their data so that only they have access to it, regardless of what device they log in with? What is best practice around this kind of solution?

I am relatively new to Flutter, and don't seem to be able to figure this out.

Here is my pubspec.yaml:

which plugin should I use to save data as key-value pair and some of them will be serialized objects? and is there are any differences in performance?

share prefrences, flutter secure storage or hive
