Check if user is logged in.
Hello, how can I check if a user is logged in?
I think that only way is to fetch accou, accout.get()
I did it like that, but it always shows the logged in screen, and throws an error
code:
class App extends StatelessWidget {
const App({super.key});
@override
Widget build(BuildContext context) {
bool isUserLoggedIn() {
try {
account().get();
return true;
} catch (error) {
return false;
}
}
Widget homeScreen = isUserLoggedIn() ? LoggedInHomeScreen() : NotLoggedInScreen();
return MaterialApp(
title: 'Outfytr',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: const Color.fromRGBO(113, 100, 231, 1)),
useMaterial3: true,
),
home: homeScreen,
);
}
}
class LoggedInHomeScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Logged In'),
),
body: Center(
child: Text('Logged In'),
),
);
}
}
class NotLoggedInScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Not Logged In'),
),
body: Center(
child: Text('Not Logged In'),
),
);
}
}```
error:
Error: AppwriteException: general_unauthorized_scope, User (role: guests) missing scope (account) (401)

pls help
Yes, it's normal for it to throw an error if there is no logged-in user. You should handle the exception
and how is that possible?
- you need to
await account.get() - you shouldn't be calling that in the build step. perhaps you need to go through some more Flutter tutorials to learn how to structure an app
in the second step you mean my bool function right?
sort of. you can't/shouldn't be calling async methods in build
Oh, I forgot about await. Anyway, I agree with Steven. Here is a brief sample, but you should use StatefulWidget instead and call your function within initState. (This is not a good practice. I recommend using a proper state management.)
Future<bool> isUserLoggedIn() async {
//---------------------------------
try {
await appApi.getAccount.get();
return true;
} on AppwriteException catch (_) {
return false;
}
}
ya, and you'd need local state to update the UI accordingly with the result of isUserLoggedIn
works thx!
