Could you pls share details of what type of architecture pattern is used over here

[lifestylenounou]

hi, thank you for the good video, i have a question can i build both of flutter app and node backend in the same IDE, vs code for example ?

[zuuylxz]

Can we fetch the token in any page directly from the shared preferences?

[sunnydagar]

my token is null
this condition use =
class _SplashScreenPageState extends State<SplashScreenPage> {
time() async {
final SharedPreferences prefs = await
var token =

Future.delayed(
const Duration(seconds: 3),
() {
if (token != null) {

context,
MaterialPageRoute(
builder: (context) => const HomePage(),
),
(route) => false);
} else {

context,
MaterialPageRoute(
builder: (context) => const LoginPage(),
),
(route) => false);
}
},
);
}

@override
void initState() {
// TODO: implement setState
super.initState();
time();
}

[CanCaner]

I get this error
Error: Superclass has no method named 'initState'.
super.initState();

where should the initState be defined rather?
and what do we need this for exactly?

Thank you for your time!

in main.dart too ?
