Where would I put an initial signup screen for new users?-CodePudding

I wanted to program a initial start up for new users, simply for them to input their initial Username, Email, possibly a password, and

If you are planning to use Firebase for authentication. There is another method you can do to check whether the user is logged in or not in your MaterialApp without using the Wrapper class. FirebaseAuth returns the current user with the following method. To do that, you need to also consider state management in your project.

initialRoute:FirebaseAuth.instance.currentUser != null ? '/home' : '/welcome',

I couldn't quite get your issue but as I understand, I advice that below code,so you can controll check new user by this approach firstly, set a bool by the sharedPreferences package

TextButton get isNewUserButton=> TextButton(onPressed: ()async{
  final prefs = await SharedPreferences.getInstance();
  prefs.setBool('isNewUser',true);
}, child: const Text("Get Started"));

then,

void main()async {
final prefs = await SharedPreferences.getInstance();
final showHomePage = prefs.getBool('isNewUser') ?? false;
  runApp(MaterialApp(
    title: 'App',
    themeMode: ThemeMode.system,
    theme: MyThemes.lightTheme,
    darkTheme: MyThemes.darkTheme,
    home: showHomePage ? MyApp() : NewUserSignPage ,
  ));
}

if user sign out you can use this code

TextButton get signOutButton=> TextButton(onPressed: ()async{
  final prefs = await SharedPreferences.getInstance();
  prefs.setBool('isNewUser',false);
}, child: const Text("Sign Out"));

You can use named routing. In your MaterialApp, you can set a boolean whether if the user is logged in or not.Such that;

 initialRoute: isUserLoggedIn == null ? '/login-screen' : '/home-screen';
