如何将json数据传递到另一个屏幕，该屏幕包含flutter中的底部选项卡导航

class DataModel {
  final String name;
  final int age;

  DataModel({required this.name, required this.age});

  factory DataModel.fromJson(Map<String, dynamic> json) {
    return DataModel(
      name: json['name'],
      age: json['age'],
    );
  }
}

import 'package:http/http.dart' as http;
import 'dart:convert';

Future<DataModel> fetchData() async {
  final response = await http.get(Uri.parse('https://example.com/data.json'));

  if (response.statusCode == 200) {
    final jsonData = jsonDecode(response.body);
    return DataModel.fromJson(jsonData);
  } else {
    throw Exception('Failed to load data');
  }
}

import 'package:flutter/material.dart';

class SourceScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ElevatedButton(
      onPressed: () {
        fetchData().then((data) {
          Navigator.push(
            context,
            MaterialPageRoute(
              builder: (context) => DestinationScreen(data: data),
            ),
          );
        });
      },
      child: Text('Go to Destination Screen'),
    );
  }
}

import 'package:flutter/material.dart';

class DestinationScreen extends StatelessWidget {
  final DataModel data;

  DestinationScreen({required this.data});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Destination Screen'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Name: ${data.name}'),
            Text('Age: ${data.age}'),
          ],
        ),
      ),
      bottomNavigationBar: BottomNavigationBar(
        items: [
          BottomNavigationBarItem(
            icon: Icon(Icons.home),
