Refer this official doc of Flutter

Code to send data to new Screen 

 Navigator.push(
      context,
      MaterialPageRoute(
        builder: (context) => DetailScreen(todo: todos[index]),
      ),
    );

Second Page/Receiving page

 class TodosScreen extends StatelessWidget {
  final List<Todo> todos;

  //requiring the list of todos
  TodosScreen({Key key, @required this.todos}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Todos'),
      ),
      //passing in the ListView.builder
      body: ListView.builder(
        itemCount: todos.length,
        itemBuilder: (context, index) {
          return ListTile(
            title: Text(todos[index].title)
          );
        },
      ),
    );
  }
}
