You can pass the model when you construct SecondScreen widget.

1. Add model to SecondScreen constructor:

   class SecondScreen extends StatefulWidget {
     final MyModel myModel;
   
     SecondScreen(MyModel myModel, {Key key}):
         super(key: key);
   ...
   }
   

2. Pass model when you construct SecondScreen in main.dart

   Navigator.push(context, new MaterialPageRoute(builder: (_) => 
     new SecondScreen(model)));
   

3. Now you can access model in _SecondScreenState via widget.myModel
