How to pass data between widgets in Flutter

Step 1 

class Datainfo {

  final String title;

  final String description;

  final List rating;

  const  Datainfo(this.title, this.description,this.rating);

}

Step 2 

import 'package:flutter/material.dart';

import 'package:props/Datainfo.dart';

import 'package:props/Profile.dart';

void main() {

  runApp(MaterialApp(

    title: "props",

    home: MyHome(),

  ));

}

class MyHome extends StatefulWidget {

  const MyHome({super.key});

  @override

  State<MyHome> createState() => _MyHomeState();

}

class _MyHomeState extends State<MyHome> {

  @override

  Widget build(BuildContext context) {

    return Container(

      child: ElevatedButton(onPressed: () {

        var userinfo = Datainfo("name", "saddam husain",[1,2,3,45,6]);

        Navigator.push(context, MaterialPageRoute(builder: (context)=>MyProfile(userinfo)));

      },

      child: Text("Click"),

      ),

    );

  }

}

Step 3

import 'package:flutter/material.dart';

import 'package:props/Datainfo.dart';

class MyProfile extends StatelessWidget {

  final Datainfo todos;

MyProfile(this.todos);

  @override

  Widget build(BuildContext context) {

    return Container(

      child: Text("${todos.title} ${todos.description} ${todos.rating.length}"),

    );

  }

}

   child: InkWell(

                      onTap: () {

                      var age = farmerData[index]['age']==null?"N/A":farmerData[index]['age'];

                      var gender = farmerData[index]['gender']=="M"?"Male":"Female";

                      var farmesData =farmerData[index]["farm"];

                      print(farmesData);

                      var userinfo =FarmerData("${farmerData[index]['name']}", "${farmerData[index]['contact_no']}","${farmerData[index]['rating'].length}","${age}","${gender}",farmesData);

                      Navigator.push(

                        context,

                        MaterialPageRoute(builder: (context) => ProfileUI2(userinfo)),

                      );

  final List name;

  Farm(this.name);
