appwrite_auth_kit's Issues

Handle Authentication Errors Effectively

I'm facing challenges in handling authentication errors. Specifically, I'm unable to find a clear and robust way to deal with errors such as wrong passwords, invalid email addresses, etc.

I have noticed that there is a nullable string named context.authNotifier.error that seems to be related to authentication errors. However, the documentation does not provide sufficient information on the possible error messages that can be encountered. Even if I had this information, relying on string validation for error handling is not considered a best practice.

I propose introducing a new enum variable, let's call it AuthError, that enumerates possible authentication error types. This would make error handling more structured and easier to manage. Developers can then listen to this enum variable and display appropriate error messages in the user interface.

How can I acess the authnotifer outside of an widget e.g in an StateNotifierProvider?

Thank you for your help!

Unhandled Exception: type 'Null' is not a subtype of type 'List<dynamic>'

I get the following error with the new Version 0.9.0

Unhandled Exception: type 'Null' is not a subtype of type 'List'

The error gets thrown in file lib/src/accounts_provider.dart, when the Appwrite SDK calls models.User.fromMap(res.data); to get the current session. When no User is logged in, the appwrite sdk throws an Null exception, which is unhandled (I think this is the Problem, but I`m not sure).

With Version 0.8.0 it works perfectly

StackTrace:

#0      new User.fromMap (package:appwrite/src/models/user.dart:87:18)
#1      Account.get (package:appwrite/services/account.dart:23:24)
<asynchronous suspension>
#2      AuthNotifier._getUser (package:appwrite_auth_kit/src/accounts_provider.dart:65:15)
<asynchronous suspension>

User redirected back to the login page after no internet connection

When their is no internet connection the state of the Auth changes to the unauthenticated and the user redirects to the login page
After making the internet available back it goes directly to the main page and the auth state is then authenticated.
It should stay authenticated or at least should stay in main page after no internet connection.
from the UX perspective it looks not good that after no internet it redirects to the Login Page, but at the back its already authenticated.

My implementation of Auth

class MainWidget extends StatelessWidget {
  const MainWidget({super.key});

  @override
  Widget build(BuildContext context) {
    final authNotifier = context.authNotifier;
    Widget widget;
    switch (authNotifier.status) {
      case AuthStatus.authenticated:
        widget = const FeedPage();
        break;
      case AuthStatus.unauthenticated:
      case AuthStatus.authenticating:
        widget = const LoginPage();
        break;
      case AuthStatus.uninitialized:
        widget = const SplashScreenWidget();
        break;
      default:
        widget = const SplashScreenWidget();
        break;
    }
    return widget;
  }
}

Get `$id` without context

Is there a way to get the $id of the current user in initState, since I can't use context there?

Here is an example:

@override
void initState() {
    super.initState();
    boatsStream = DB.boat.streamBoats(uid); // Initialize the stream
}

I somehow need to get the users id here. But it's not only initState functions where I need to get the $id without context, for example in the toMap function of some of my models I also need it.

I'm getting error when I was trying to use package with GetX package

======== Exception caught by widgets library =======================================================
The following assertion was thrown building MainScreen(dirty, dependencies: [FlAppwriteAccountKit]):
setState() or markNeedsBuild() called during build.

This Overlay widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase.
The widget on which setState() or markNeedsBuild() was called was: Overlay-[LabeledGlobalKey<OverlayState>#c5b77]
  state: OverlayState#cee5b(entries: [OverlayEntry#62e83(opaque: true; maintainState: false), OverlayEntry#a96c4(opaque: false; maintainState: true), OverlayEntry#82e01(opaque: false; maintainState: false), OverlayEntry#fdc08(opaque: false; maintainState: true)])

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.

Login (check email is verified).
Singup (send verification email).
Resend verification email.

I don't know what it is the best way to tackle this, but I suggest to consider these options:

Have two different AuthStatus states: authenticatedVerified and authenticatedNotVerified instead of authenticated.
Include and optional parameter notifyListeners = true in createSession and deleteSession, so these methods can be used for signing up and resending verification emails.
