Animate ListItems into another List within the Same Page - flutter

Question

I’m trying to recreate an animation from dribbble (link: https://dribbble.com/shots/16587569-Planner-App) on the app I’m working on.
What I currently have is just a listview builder and a DayView calendar from (calendar pubspec link) switching on whether the calendar is month view or weekly view (I am using Table Calendar for this).
Here is a snippet of the code:
calendarFormat == CalendarFormat.week ?
Container(
alignment: Alignment.topCenter,
child: DayView(
key: calendarKey,
controller: eventController,
dayTitleBuilder: (thisDay){
return Container(
alignment: Alignment.centerLeft,
padding: const EdgeInsets.only(left: 10,bottom: 10),
child: Text(
"Upcoming Events",
style: TextStyle(
color: kGrey,
fontSize: 14,
fontWeight: FontWeight.w600
),
),
);
},
eventTileBuilder: (date, events, boundry, start, end) {
// CalendarEventData eventData = events[0];
return Padding(
padding: const EdgeInsets.only(left: 10),
child: Container(
width: width,
padding: const EdgeInsets.all(10),
alignment: Alignment.centerLeft,
decoration: BoxDecoration(
color: kOrange,
borderRadius: const BorderRadius.horizontal(left: Radius.circular(20)),
),
child: const Text(
"Data",
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.w600
),
),
),
);
},
width: width,
timeLineWidth: 60,
backgroundColor: Colors.white,
showVerticalLine: false,
showLiveTimeLineInAllDays: true,
minDay: DateTime(2022,01,01),
maxDay: DateTime(2022,12,30),
initialDay: _focusedDay,
heightPerMinute: 1.0,
eventArranger: const SideEventArranger(),
onEventTap: (events, date) => print(events),
onDateLongPress: (date) => print(date),
onPageChange: (date,_)=> {
_onDaySelected(date, _focusedDay)
},
)
) :
ValueListenableBuilder<List<BolaEventData>>(
valueListenable: _selectedBolaEvents,
builder: (context, value, _) {
return Listview.builder(
itemCount: dayEvent.length,
return Container(
width: width*.1, child: Text("Data")
);
)
}
)
