I’ve implemented an app on Flutter framework. I’m new to flutter and I don’t know how to pass the data to new screen. Someone said me that you should use Named routes in your app so I tried it. But now I don’t know how to pass the data from one screen to another screen.

These are the routes in my MaterialApp:

routes: {
    '/': (context) => FirstPage(),
    '/second': (context) => SecondPage(),
    '/third': (context) => ThirdPage(),
},

And this is how I navigate to new screen normally:

onPressed: () { 
    Navigator.pushNamed(context, '/second');
},

I want to pass the data to new screen when navigate to new screen.
