How to push scheduled notification with flutter?

Question

I am using awesome_notification package for pushing notifications through my app. I have almost completed everything but I am stuck right at the edge.

So the thing I want is the code for pickSchedule.

First I want to pick a weekday:

Secondly I want to set the time:

After selecting the weekday and time I want to push the scheduled notification on that particular time.

Here is the tutorial video: https://www.youtube.com/watch?v=JAq9fVn3X7U&t=3420s The code for the particular thing that I want is on time stamp 56:59 of the video.

I could retrieve only this much of the code:

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

class NotificationWeekAndTime {
  final int dayOfTheWeek;
  final TimeOfDay timeOfDay;

  NotificationWeekAndTime({
    required this.dayOfTheWeek,
    required this.timeOfDay,
  });
}

Future<NotificationWeekAndTime?> pickSchedule(
  BuildContext context,
) async {
  List<String> weekdays = [
    'Mon',
    'Tue',
    'Wed',
    'Thu',
    'Fri',
    'Sat',
    'Sun',
  ];
  TimeOfDay? timeOfDay;
  DateTime now = DateTime.now();
  int? selectedDay;

  await showDialog(
    context: context,
    builder: (context) {
      return AlertDialog(
        title: Text(
          'Select day of the week',
          style: TextStyle(
            fontFamily: GoogleFonts.shadowsIntoLight().fontFamily,
            letterSpacing: 1.5,
          ),
          textAlign: TextAlign.center,
        ),
        content: Wrap(
          alignment: WrapAlignment.center,
          spacing: 3,
          children: [
            for (int index = 0; index < weekdays.length; index++)
              ElevatedButton(
                onPressed: () {
                  selectedDay = index + 1;
                  Navigator.pop(context);
                },
                style: ButtonStyle(
                  backgroundColor:
                      MaterialStateProperty.all<Color>(Colors.teal),
                ),
                child: Text(
                  weekdays[index],
                  style: TextStyle(
                    color: Colors.white,
                    fontFamily: GoogleFonts.shadowsIntoLight().fontFamily,
                    letterSpacing: 1.1,
                  ),
                ),
              ),
          ],
        ),
      );
    },
  );
}

I need rest of the code to finish my project.

Here is rest of the code: [NotificationWeekAndTime]

  if (selectedDay != null) {
    timeOfDay = await showTimePicker(
        context: context,
        initialTime: TimeOfDay.fromDateTime(
          now.add(
            Duration(minutes: 1),
          ),
        ),
        builder: (BuildContext context, Widget? child) {
          return Theme(
            data: ThemeData(
              colorScheme: ColorScheme.light(
                primary: Colors.teal,
              ),
            ),
            child: child!,
          );
        });

    if (timeOfDay != null) {
      return NotificationWeekAndTime(
          dayOfTheWeek: selectedDay!, timeOfDay: timeOfDay);
    }
  }
  return null;
