This is my splash screen
class SplashState extends State<SplashScreen>{
bool isLogged = false;
startTime(){
return new Timer(Duration(milliseconds: 3000), navigateUser);
}
#override
void initState() {
super.initState();
getStoredValue();
}
void getStoredValue() async{
SharedPreferences prefs = await SharedPreferences.getInstance();
if (!prefs.containsKey('isLoggin')) {
prefs.setBool('isLoggin', false);
print("login set to False");
}
isLogged = prefs.getBool('isLoggin');
print("Status in splash -----------$isLogged");
startTime();
}
#override
Widget build(BuildContext context) {
SystemChrome.setEnabledSystemUIOverlays([]);
return Container(
height: double.infinity,
width: double.infinity,
decoration: BoxDecoration(
gradient:LinearGradient(
begin: Alignment.topLeft,
end: Alignment.bottomRight,
colors: <Color>[
colorStyle.splashPink,
colorStyle.splashOrange,
],
)
),
child: Center(
child: Image.asset("assets/images/splash_logo.png", height: 85.0),
),
);
}
void navigateUser() {
if (isLogged == true) {
Navigator.of(context).pushReplacement(
PageRouteBuilder(pageBuilder: (_, __, ___) => Home()));
}
else {
Navigator.of(context).pushReplacement(
PageRouteBuilder(pageBuilder: (_, __, ___) => Login()));
}
}
}
Logout
void logoutUser()async{
LogoutUser objLog = await createPost(logoutUrl,body);
if(objLog.statusCode == 10000){
print(("response is $resp"));
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setBool('isLoggin', false);
Navigator.pushReplacement(context, MaterialPageRoute(builder: (context) => Login()));
}
else showToast(objLog.message, duration: Toast.LENGTH_LONG);
}

Try to use shared preference to store as login key and check if it is true then go to main screen or else redirect to login screen.
First of all add shared preference dependency in your pubspec.yaml
dependencies:
flutter:
sdk: flutter
shared_preferences: ^0.5.6+2
SplashScreen.dart
This is first screen where we are check that if isLogin is true then go to HomeScreen or else redirect to LoginScreen
_autoLogin() async {
SharedPreferences prefs = await SharedPreferences.getInstance();
if (!prefs.containsKey('isLogin')) {
prefs.setBool('isLogin', false);
}
if (prefs.getBool('isLogin')) {
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => HomeScreen(),
));
} else {
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => LoginScreen(),
));;
}
}
LoginScreen.dart
_setIsLogin() async {
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setBool('isLogin', true);
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => HomeScreen(),
));
}
MaterialButton(
minWidth: MediaQuery.of(context).size.width,
padding: EdgeInsets.fromLTRB(20.0, 10.0, 20.0, 10.0),
onPressed: () {
_setIsLogin();
},
child: Text("LOGIN",
textAlign: TextAlign.center,
style: style.copyWith(
color: Colors.white,
fontWeight: FontWeight.bold,
fontSize: 18.0)),
),
HomeScreen.dart
Set isLogin as false when click on Logout
_logout() async {
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setBool('isLogin', false);
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => LoginScreen(),
));
}
I hope this can help you!
