Firebase email verification Flutter - firebase

Question

I know this question has been asked a lot and I have spent a lot of time reading and trying to implement the answers. So I am trying to get the response from isEmailVerified from Firebase Auth to work and it does work but right now it always returns false unless I refresh the app or close it and reopen it. which is obviously a bad user experience. How do I get the response to update without having to close the app.
here is the relevant pieces of code.
Future<bool> isEmailVerified() async {
FirebaseUser user = await _auth.currentUser();
if (user == null) {
return false;
} else {
await user.reload();
user = await _auth.currentUser();
return user.isEmailVerified;
}
}
main.dart
child: Consumer<Auth>(
builder: (_, auth, __) => MaterialApp(
theme: Provider.of<ThemeNotifier>(context).getTheme(),
home: FutureBuilder(
future: Future.wait([auth.isEmailVerified(), auth.tryAutoLogin()]),
builder: (BuildContext ctx, AsyncSnapshot authResultSnapshot) =>
authResultSnapshot.connectionState == ConnectionState.done
? authResultSnapshot.data[1]
? authResultSnapshot.data[0]
? HearingsScreen()
: SplashScreen(
emailVerified: true,
)
: LoginScreen()
: SplashScreen(),
),
It is not returning true until I restart the app
Things I have tried besides this:
1) await user.getIdToken(refresh: true);
2) sign user out then back in
3) firebase_user_stream package
Any help is appreciated.

I have implemented the same scenario in a splash screen with below code, you can change it as per your requirement. :
//To check is User is logged in
Future<bool> isLoggedIn() async {
FirebaseUser user = await _fireBaseAuth.currentUser();
if (user == null) {
return false;
}
return user.isEmailVerified;
}
and
countDownTime() async {
return Timer(
Duration(seconds: splashDuration),
() async {
if (await userAuth.isLoggedIn()) {
Navigator.pushReplacement(
context,
ScaleRoute(
widget: HomeScreen(),),
);
}
} else {
Navigator.pushReplacement(
context,
ScaleRoute(
widget: LoginScreen(),),
);
}
},
);
}
and
#override
void initState() {
super.initState();
countDownTime();
}
Update
One needs to implement isEmailVerified in initState() function periodically which can be the ideal approach to execute the verification with firebase.
bool _isUserEmailVerified;
Timer _timer;
#override
void initState() {
super.initState();
// ... any code here ...
Future(() async {
_timer = Timer.periodic(Duration(seconds: 10), (timer) async {
await FirebaseAuth.instance.currentUser()..reload();
var user = await FirebaseAuth.instance.currentUser();
if (user.isEmailVerified) {
setState((){
_isUserEmailVerified = user.isEmailVerified;
});
timer.cancel();
}
});
});
}
#override
void dispose() {
super.dispose();
if (_timer != null) {
_timer.cancel();
}
}
