After new Login app show old user data from firebase - flutter

Question

I am trying to display current user data from Firebase, and it works totally fine, but when I logout and login with a new email ID, the app also shows previous user data instead of new user login data.
My signIn function in Signin page
class LoginPage extends StatefulWidget {
//when user is login then save their userid and after use this for fetching current user data
//this help in StudentData.dart page
var userId;
#override
State<LoginPage> createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
final emailController = TextEditingController();
final passwordController = TextEditingController();
//for Validation
final _key = GlobalKey<FormState>();
//for geeting input and store email & password
var email = "";
var password = "";
//for Loading Indicator
bool isLodaing = false;
//for login
Future userLogin() async {
//check internet is on or not
final ip = context.read<InternetProvider>();
await ip.checkInternetConnection();
//for checking Internet
if (ip.hasInternet == false) {
openSnackbar(context, "Check your internet connection", Colors.red);
} else {
try {
UserCredential userCredential = await FirebaseAuth.instance
.signInWithEmailAndPassword(email: email, password: password);
//when user loged in that time save user id that help after for fetch data in StudentData.dart page
// widget.userId = userCredential.user!.uid;
setState(() {
widget.userId = userCredential.user!.uid;
print("User id is : " + userCredential.user!.uid);
});
print("Widget User id is : " + widget.userId);
//show succuful log-in meesage
openSnackbar(
context, "Log-in Successfull", Color.fromARGB(255, 70, 213, 92));
//after login go to profile Page
Navigator.pushReplacement(
context, MaterialPageRoute(builder: (context) => FirstPage()));
} on FirebaseAuthException catch (e) {
//for no user Found
if (e.code == 'user-not-found') {
//for stoping the loading indicator when user get this error
Future.delayed(
Duration(seconds: 0),
() {
setState(() {
isLodaing = false;
});
},
);
//show Snack Bar when this error occur
openSnackbar(context, "No User Found for this e-mail", Colors.red);
}
//for Wrong Password
else if (e.code == 'wrong-password') {
//for stoping the loading indicator when user get this error
Future.delayed(
Duration(seconds: 0),
() {
setState(() {
isLodaing = false;
});
},
);
//show Snack Bar when this error occur
openSnackbar(context, "Wrong Password", Colors.red);
