Opening a screen out the result of a statement - flutter

Question

enter code hereI want to open a screen to add extra information if it is not set yet. So after the user is logged in I check if the extra info is set. If not I want it to go to a screen to fill in the info. If the user is done it should go to a "Homescreen". If the user info is already set it should immediately go to the home screen.
I already tried to just go to the extra info form and then Navigator.push to the home screen but then it has difficulties with logging out. I searched for a long time but can not find anything.
class CampPage extends StatelessWidget {
final String email;
final String uid;
const CampPage({super.key, required this.email, required this.uid});
#override
Widget build(BuildContext context) {
return FutureBuilder(
// ignore: unrelated_type_equality_checks
future: context.read<UserProvider>().exists(uid) == true
? null
: Future.delayed(Duration.zero, () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => NewUserPage(email: email, userId: uid),
),
);
}),
builder: (context, snapshot) => Scaffold(
drawer: const DrawerHomePage(),
appBar: AppBar(
title: const Text("Camp Page"),
),
body: Column(
children: const [
Text("nieuwe features"),
],
),
),
);
}
}
this is one of the things I try but the NewUserPage always pops up and I only want it to pop up if context.read<UserProvider>().exists(uid) == false
also the solution mentioned does not work for me. I think because there is a screen in between the login and logout (The form screen) the logout function does not work properly.
`
class UserPage extends StatelessWidget {
const UserPage({super.key});
#override
Widget build(BuildContext context) {
return Scaffold(
body: ElevatedButton(
child: const Text("Submit"),
onPressed: () {
//Log out of Firestore Authentication
},
),
);
}
}
class NewForm extends StatelessWidget {
const NewForm({super.key});
#override
Widget build(BuildContext context) {
return Scaffold(
body: ElevatedButton(
child: const Text("Submit"),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => const UserPage()),
);
},
),
);
}
}
Widget build(BuildContext context) {
return FutureBuilder(
future: context.read<UserProvider>().exists(uid)
builder: (context, snapshot) {
if (snapshot.hasdata){
if (snapshot.data == true) {
return const UserPage();
} else {
return const NewForm();
}
}
else // show a proggress bar
}
);
}
`
Does someone still have another solution?

I think you should do this:
Widget build(BuildContext context) {
return FutureBuilder(
future: context.read<UserProvider>().exists(uid)
builder: (context, snapshot) {
if (snapshot.hasdata){
if (snapshot.data == true) // then the user exist
else // the user doesn't exist
}
else // show a proggress bar
}
);
}
