Question

I want to develop a logout button that will send me to the log in route and remove all other routes from the Navigator. The documentation doesn\'t seem to explain h

Answer 1

This is working for me. Actually, I was working with bloc but my issue was login screen bloc. It was not updating after logout. It was holding the previous model data. Even, I entered the wrong entry It was going to Home Screen.

Step 1:

Navigator.of(context).pushNamedAndRemoveUntil(
        UIData.initialRoute, (Route route) => false);

where, UIData.initialRoute = "/" or "/login"

Step 2:

It's working to refresh the screen. If you are working with Bloc then It will very helpful.

runApp(MyApp());

where, MyApp() is the root class.

Root class (i.e. MyApp) code

class MyApp extends StatelessWidget {

  final materialApp = Provider(
      child: MaterialApp(
          title: UIData.appName,
          theme: ThemeData(accentColor: UIColor().getAppbarColor(),
            fontFamily: UIData.quickFont,
          ),
          debugShowCheckedModeBanner: false,
          //home: SplashScreen(),
          initialRoute: UIData.initialRoute,
          routes: {
            UIData.initialRoute: (context) => SplashScreen(),
            UIData.loginRoute: (context) => LoginScreen(),
            UIData.homeRoute: (context) => HomeScreen(),
          },
          onUnknownRoute: (RouteSettings rs) => new MaterialPageRoute(
              builder: (context) => new NotFoundPage(
                appTitle: UIData.coming_soon,
                icon: FontAwesomeIcons.solidSmile,
                title: UIData.coming_soon,
                message: "Under Development",
                iconColor: Colors.green,
              )
          )));

  @override
  Widget build(BuildContext context) {
    return materialApp;
  }
}

void main() => runApp(MyApp());

Here is My Logout method,

void logout() async {
    SharedPreferences preferences = await SharedPreferences.getInstance();
    preferences.clear();

    // TODO: we can use UIData.loginRoute instead of UIData.initialRoute
    Navigator.of(context).pushNamedAndRemoveUntil(
        UIData.initialRoute, (Route route) => false);
    //TODO: It's working as refresh the screen
    runApp(MyApp());
  }
