class MyApp extends StatelessWidget {
    // This widget is the root of your application.
    @override
    Widget build(BuildContext context) {
        return new MaterialApp(
            title: 'Yaip',theme: new ThemeData(
                primarySwatch: Colors.pink,brightness: Brightness.light
            ),home: new VerifyPhoneNumber(),routes: <String,WidgetBuilder>{
                '/verified': (BuildContext context) =>  new MobileNumberVerified(),'/setupprofile': (BuildContext context) =>  new SetUpProfile()
            },);
    }
}
