How can i check if a user is logged in?

Summary

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

like that?

Dart

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

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

Dart

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"),
            ),
          ],
        ),
      ),
    );
  }
}

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

So it should be a statusful widget?

Drake

but the authenticated checker still does not work

code:

Dart

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())
          ],
        ),
      ),
    );
  }
}```

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)

Drake

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