Answer 1

class FirstPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var from = "Five", to = "Ten";
    return SecondPage(from: from, to: to);
  }
}



class SecondPage extends StatefulWidget {
  final from, to;
  const SecondPage({Key key, this.from, this.to}) : super(key: key);
  @override
  _SecondPageState createState() => _SecondPageState();
}

class _SecondPageState extends State<SecondPage> {
  var newFrom = "", newTo = "";

  @override
  void initState() {
    setState(() {
      newFrom = widget.from;
      newTo = widget.to;
    });
    super.initState();
  }
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Text("$newFrom $newTo"),
    );
  }
}
