Next Prayer by Time Nor Working

[wael93]

I have this code

  final myCoordinates = Coordinates(21.416667938232425, 39.81666564941406); // Replace with
    final MaccaTime = Duration(hours: 3);
    final date = DateComponents.from(DateTime.now());


    final params = CalculationMethod.umm_al_qura.getParameters();
    params.madhab = Madhab.hanafi;
    params.adjustments.fajr = -1;
    final prayerTimes =PrayerTimes(myCoordinates, date, params, utcOffset: MaccaTime);
   
    var nextPrayerTimes = prayerTimes.nextPrayer();
    print("nextPrayerTimes "+ nextPrayerTimes.toString() );

    final nextPrayerTime = prayerTimes.timeForPrayer(nextPrayerTimes);

  
    final startTime = DateTime(nextPrayerTime.year, nextPrayerTime.month,
        nextPrayerTime.day,
        nextPrayerTime.hour,
        nextPrayerTime.minute);
    final currentTime = DateTime.now();

    final diff_dy = startTime.difference(currentTime).inDays;
    final diff_hr = startTime.difference(currentTime).inHours;
    final diff_mn = startTime.difference(currentTime).inMinutes;
    final diff_sc = startTime.difference(currentTime).inSeconds;

    print(diff_dy);
    print(diff_hr);
    print(diff_mn);
    print(diff_sc/60);

it's Should Show next player is Isha
but it shows Asr
