How to check if user is logged in.

How can i check if a user is logged in?

TL;DR

The user wants to know how to check if a user is logged in and has encountered an error related to authorization. They have shared their code and are seeking assistance to fix the issue. One suggestion is to update the state to handle the error and refresh the UI accordingly. Additional tutorials and practice with Flutter state fundamentals are recommended. Here is a potential solution: - Update the `LoggedIn` widget to extend `StatelessWidget`. - Try calling `account().get()` and handle the exception by returning `NotLoggedIn()` if an error is thrown. - In the `Home` widget, add a logout button that calls `account().deleteSessions

Maybe this will help: https://github.com/appwrite/appwrite/discussions/3938#discussioncomment-3746725

like that?

TypeScript

try {
account.get();
} catch(error) {
print("not logged in");
}```

Yep! You can also add the language to enable syntax highlighting

i actually did haha

Oh sorry. Dart highlighting doesn't work on mobile 😑

to logout i need to use account.deleteSessions()right?

but then it will still show my logged in screen

Depends on how you build your app...

if this would be right it would show the not logged in screen

TypeScript

class LoggedIn extends StatelessWidget {

  @override
  Widget build(BuildContext context) {

    try {
      account().get();

      return Home(title: 'Outfytr');
    } catch(error) {
      return NotLoggedIn();
    }
  }
}

class Home extends StatefulWidget {
  final String title;

  Home({required this.title});

  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Align(
        alignment: Alignment.topRight,
        child: Row(
          mainAxisAlignment: MainAxisAlignment.end,
          children: [
            ElevatedButton(
              onPressed: () {
                account().deleteSessions();
              },
              child: Text("Logout"),
            ),
          ],
        ),
      ),
    );
  }
}

You need to handle state and update the app accordingly...

and how (sorry im new to flutter)

It might be good to find some additional tutorials or so for flutter then

i've watched some, but i dont get the mistake

In order to refresh the UI, you need to update state

So it should be a statusful widget?

Yes

but the authenticated checker still does not work

code:

TypeScript

class LoggedIn extends StatefulWidget {

  @override
  _LoggedInStatus createState() => _LoggedInStatus();

}

class _LoggedInStatus extends State<LoggedIn> {
  @override
  Widget build(BuildContext context) {

    try {

      account().get();
      return NotLoggedIn();
    } catch(error) {
      return Home();
    }
  }
}

class Home extends StatefulWidget {

  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Outfytr"),
      ),
      body: Align(
        alignment: Alignment.topRight,
        child: Row(
          mainAxisAlignment: MainAxisAlignment.end,
          children: [
            ElevatedButton(
              onPressed: () {
                account().deleteSessions();
                Navigator.pushReplacement(
                  context,
                  MaterialPageRoute(builder: (context) => NotLoggedIn()),
                );
              },
              child: Text("Logout"),
            ),
            Text(User.name().toString())
          ],
        ),
      ),
    );
  }
}```

I think you need some more tutorials and practice with state fundamentals in flutter

thats also a fix, somehow xD

after some working I think the error that i get is not on the widget site, i think, that it's the way I check the logged in. Do you know the fix?

error: Error: AppwriteException: general_unauthorized_scope, User (role: guests) missing scope (account) (401)

If an exception is thrown they aren't logged in....so then you need to update state based on that
