Error when trying on PageView and PageController

I wrote the code same as tutorial, it ran normally, but I found an issue, when I trying to tap on item on the bottom navbar the page doesn't changed, but when I swipe left or right the page changed normally.

Please kindly check my codes below, thank you :)


import 'package:flutter/material.dart';
import 'package:bottom_navy_bar/bottom_navy_bar.dart';

class Home extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return _HomeState();
  }
}

class _HomeState extends State<Home> {
  int _currentIndex = 0;
  PageController _pageController;

  @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('MAL MALIOBORO'), centerTitle: true),
      body: SizedBox.expand(
        child: PageView(
          controller: _pageController,
          onPageChanged: (index) {
            setState(() => _currentIndex = index);
          },
          children: <Widget>[
            Container(
              color: Colors.blueGrey,
            ),
            Container(
              color: Colors.redAccent,
            ),
            Container(
              color: Colors.lightGreenAccent,
            ),
            Container(
              color: Colors.blueAccent,
            ),
          ],
        ),
      ),
      bottomNavigationBar: BottomNavyBar(
        selectedIndex: _currentIndex,
        showElevation: true,
        onItemSelected: (index) {
          setState(() => _currentIndex = index);
          _pageController.jumpToPage(index);
          _pageController.animateToPage(index,
              duration: Duration(microseconds: 300), curve: Curves.ease);
        },
        items: <BottomNavyBarItem>[
          BottomNavyBarItem(title: Text('Home'), icon: Icon(Icons.home)),
          BottomNavyBarItem(title: Text('Inbox'), icon: Icon(Icons.inbox)),
          BottomNavyBarItem(title: Text('Chat'), icon: Icon(Icons.chat_bubble)),
          BottomNavyBarItem(title: Text('Profile'), icon: Icon(Icons.person)),
        ],
      ),
    );
  }
}
