我已经实现了自定义水平日历通过列表视图和这个列表视图日期和天显示在每个索引到365天
但如何改变滚动动作时达到和改变每个月。标题（月&年）也需要改变与scrollcontroller或任何其他方式来更新标题，如下面给出的视频

import 'package:flutter/material.dart';

class Calendartimeline extends StatefulWidget {
  @override
  _CalendartimelineState createState() => _CalendartimelineState();
}

class _CalendartimelineState extends State<Calendartimeline> {
  late final ValueNotifier<DateTime> selectedDate;
  late final ValueNotifier<DateTime> datechanged; // TO tracking date

  int currentDateSelectedIndex = 0; //For Horizontal Date
  ScrollController scrollController =
      ScrollController(); //To Track Scroll of ListView

  List<String> listOfMonths = [
    "Jan",
    "Feb",
    "Mar",
    "Apr",
    "May",
    "Jun",
    "Jul",
    "Aug",
    "Sep",
    "Oct",
    "Nov",
    "Dec"
  ];

  List<String> listOfDays = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"];
  @override
  void initState() {
    selectedDate = ValueNotifier(DateTime.now());
    datechanged = ValueNotifier(DateTime.now()
        
        );
    scrollController.addListener(() {
      
    });

    super.initState();
  }

  

  @override
  Widget build(BuildContext context) {
    return
       

        ValueListenableBuilder<DateTime>(
            valueListenable: selectedDate,
            builder: (context, datetime, _) {
              return
                  

                  Column(
                children: [
                  
                  SizedBox(height: 10),
                  

                  Container(
                      margin: EdgeInsets.only(left: 10),
                      height: 150,
                      child: Container(
                          child: ListView.separated(

                        separatorBuilder: (BuildContext context, int index) {
                          return SizedBox(width: 25);
                        },
                        itemCount: 365,
                        controller: scrollController,
                        scrollDirection: Axis.horizontal,
                        itemBuilder: (BuildContext context, int index) {
                          return
