How do I set my hour and minute from a variable inside TZDateTime?:Flutter

I schedule user notifications. It works well, but I want to add the hour and minute that come from the user only I have two variables, the hour and the minute, but I do not know where to put the variables. I tried to put them with the year, month, and day, but to no avail. Can I achieve that?

Example:

    var  schduelTime =  tz.TZDateTime(
          tz.local,
          currentzone.year,
          currentzone.month,
          currentzone.day,
          My_hour,
          My_minute,

        );

//Code

import 'package:adhdhkar_muslim/virb_uli.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:timezone/data/latest.dart' as tz;
import 'package:timezone/timezone.dart' as tz;
import 'dart:math';
import 'package:adhdhkar_muslim/virb_uli.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:timezone/data/latest.dart' as tz;
import 'package:timezone/timezone.dart' as tz;
import 'package:flutter_timezone/flutter_timezone.dart';
import 'virb_uli.dart';
class NotificationService {
  static FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

   static Future init()async{
    // ignore: unused_local_variable
    InitializationSettings settings = const InitializationSettings(
      android: AndroidInitializationSettings('@mipmap/ic_launcher'),
      iOS: DarwinInitializationSettings(),
    );

    flutterLocalNotificationsPlugin.initialize(
      settings,
      
     // onDidReceiveBackgroundNotificationResponse:(details) {},
      //onDidReceiveNotificationResponse:(details){},
    );

   }

static void showBasicNotification() async {
  const AndroidNotificationDetails android = AndroidNotificationDetails(
    'id 3',
    "schdulrd Notf",
    importance: Importance.max,
    priority: Priority.high,

  );
  NotificationDetails details = const NotificationDetails(
    android: android,
  );
  tz.initializeTimeZones();
 
 var  currentzone = tz.TZDateTime.now(tz.local);
 
 var  schduelTime =  tz.TZDateTime(
          tz.local,
          currentzone.year,
          currentzone.month,
          currentzone.day,
          19,
          30,

        );
if (schduelTime.isBefore(currentzone)) {

 schduelTime = schduelTime.add(const Duration(days: 1));
   //schduelTime = schduelTime.add(const Duration(hours: 1));
   
 }
await flutterLocalNotificationsPlugin.zonedSchedule(
   1,
  "اذكار الصباح ",
  "الله اكبر",
  schduelTime
   ,
  details,
   uiLocalNotificationDateInterpretation:UILocalNotificationDateInterpretation.absoluteTime);

}

}

I don’t want to add the time manually like in the code. I don’t want that

    This code works when the current date is added.

        var  currentzone = DateTime.now().copyWith(hour:17,minute:56);
 
 var  schduelTime =  tz.TZDateTime.from(
         currentzone,
          tz.local,

        );

    But it gives this error: Exception has occurred. ArgumentError (Invalid argument (scheduledDate): Must be a date in the future: Instance of 'TZDateTime')

    Maybe you can use the ‘add’ method as shown in

    schduelTime = schduelTime.add(const Duration(days: 1));

    But you can replace the duration with a simple equation that subtracts the date and time that the user enters from the DateTime.now().

    Like now the time is 05:30 am and wanna it 02:30 pm so subtract it and the result will be 3 hours.
    So you added this 3 hours with ‘add’ method.
