Is there is a way to pop my screen automatically? - flutter

Question

In my app "see the structure image" I use a wrapper to navigate the StartUp page or HomePage/NewsFeed page. On the startup page, I have 2 options 1. User Login 2. Volunteer Login. When I use any of these pages to log in its successful to login but page changes in the background. My login page doesn't pop out. I use Navigator.of(context).pop() but nothing works
Main Page code
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of This application.
#override
Widget build(BuildContext context) {
return StreamProvider<User>.value(
value: Authentication().user,
child: MaterialApp(
title: 'Flutter Demo',
theme: ThemeData().copyWith(
scaffoldBackgroundColor: Color(0XFF00B8A9),
canvasColor: Color(0XFF00B8A9),
cursorColor: Color(0XFF00B8A9),
),
initialRoute: Wrapper.id,
routes: {
Wrapper.id: (context) => Wrapper(),
StartUpScreen.id: (context) => StartUpScreen(),
SignIn.id: (context) => SignIn(),
VolunteerLogin.id: (context) => VolunteerLogin(),
Registration.id: (context) => Registration(),
VolunteerHome.id: (context) => VolunteerHome(),
},
),
);
}
}
Wrapper Page Code
class Wrapper extends StatelessWidget {
static String id = "Wrapper";
#override
Widget build(BuildContext context) {
// Check if the user login or not and based on condition send him to different screen
final user = Provider.of<User>(context);
if(user == null){
return StartUpScreen();
}else{
return NewsFeed();
}
}
}
StartUp page code
class StartUpScreen extends StatefulWidget {
static String id = "Start_Up_Screen";
#override
_StartUpScreenState createState() => _StartUpScreenState();
}
class _StartUpScreenState extends State<StartUpScreen> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Column(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
GestureDetector(
onTap: () {
Navigator.pushNamed(context, SignIn.id);
},
child: ReusableButton(
containerColor: kPrimaryButtonColor,
buttonChild: Text(
"User Login",
style: TextStyle(
fontFamily: 'Roboto',
fontSize: 15.0,
),
),
),
),
SizedBox(
height: 40.0,
width: 30.0,
),
GestureDetector(
onTap: () =>
Navigator.pushNamed(context, VolunteerHome.id),
child: ReusableButton(
containerColor: kSOSButtonColor,
buttonChild: Text(
"Volunteer Login",
style: TextStyle(
fontFamily: 'Roboto',
fontSize: 15.0,
color: Colors.white,
),
),
),
),
],
)
],
),
),
);
}
}
Login Page code
class SignIn extends StatefulWidget {
static String id = "Sign_In";
#override
_SignInState createState() => _SignInState();
}
class _SignInState extends State<SignIn> {
Authentication _authentication = Authentication();
final _formKey = GlobalKey<FormState>();
// text field state
String email = '';
String password = '';
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
padding: EdgeInsets.symmetric(horizontal: 30.0),
child: Form(
key: _formKey,
autovalidate: true,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
TextFormField(
decoration: kInputFormFieldDecoration.copyWith(hintText: 'email'),
validator: (val) => val.isEmpty ? 'Enter an email' : null,
onChanged: (val) {
setState(() => email = val);
},
),
SizedBox(height: 20.0),
TextFormField(
decoration: kInputFormFieldDecoration.copyWith(hintText: 'password'),
obscureText: true,
validator: (val) => val.length < 6 ? 'Enter a password 6+ chars long' : null,
onChanged: (val) {
setState(() => password = val);
},
),
SizedBox(height: 20.0),
RaisedButton(
color: Colors.pink[400],
child: Text(
'Sign In',
style: TextStyle(color: kPrimaryButtonColor),
),
onPressed: () async {
await _authentication.signInWithEmailAndPassword(email, password);
},
)
],
),
),
),
);
}
}

Where do you use Navigator.of(context).pop() I see you using Navigator.pushNamed(context, routeName); which would be why your screen is not popping off try changing this too.
Navigator.of(context).popAndPushNamed(routeName)
If you have tried this already let me know and I will try and help you further.
