Answer 1

You can define your var at top of the class to make them accessible in the class

String user='';

then call your loginStatus in initState()

@override
void initState() {
  super.initState();
  loginStatus(); 
}

then append your loginstatus as follows

void loginStatus() async {
  final SharedPreferences prefs = await SharedPreferences.getInstance();
  setState()({
    user = prefs.getString('username');
    pasw = prefs.getString('password');
  }); 
}

now you can use Text("$user") anywhere.
