Flutter pageview navigate - flutter

Question

How can I use pageController.jumptopage(0) method on button in Page3.dart ? Is it possible? Full example code:
main.dart file
import 'package:flutter/material.dart';
import 'package:test_app/page1.dart';
import 'package:test_app/page2.dart';
import 'package:test_app/page3.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
late PageController pageController;
int selectedPage = 0;
final List<Widget> pagesList = [const Page1(), const Page2(), const Page3()];
#override
void initState() {
super.initState();
pageController = PageController();
}
#override
void dispose() {
pageController.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: PageView(
controller: pageController,
children: pagesList,
onPageChanged: (index) {
setState(() => selectedPage = index);
},
),
);
}
}
Page3.dart file
import 'package:flutter/material.dart';
class Page3 extends StatelessWidget {
const Page3({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
alignment: Alignment.center,
decoration: const BoxDecoration(
color: Colors.red,
),
child: ElevatedButton(
child: const Text('Button'),
onPressed: () {
// pageController.jumptopage(0); <<< use this
}),
);
}
}
