Answer 1

Make sure route table mentioned in same context:

  @override
  Widget build(BuildContext context) {

    return MaterialApp(
       home: FutureBuilder(future: _isUserLoggedIn(),
                   builder: (ctx, loginSnapshot) => 
                   loginSnapshot.connectionState == ConnectionState.waiting ?
                   SplashScreen() : loginSnapshot.data == true ?  AppLandingScreen(): SignUpScreen()
                ),
       routes: {
         AppLandingScreen.routeName: (ctx) => AppLandingScreen(),
      },

    );



  }

I faced this issue because i define route table in different build method.
