Describe the bug

The test for calculating prayer times in Egypt is failing due to an inconsistency in the Dhuhr prayer time.
Here's a breakdown of the issue:

Test Result:

Expected Dhuhr Time: 11:53 AM
Actual Dhuhr Time: 11:54 AM
Difference: 1 minute later than expected
The ASR prayer is also included, but the difference is 1 hour and 1 minute.

this is the successful state

test('Test Prayer Time in Egypt', () {
    final coordinates = Coordinates(26.0590358, 32.2320519);
    final date = DateComponents.from(DateTime.now());
    final params = CalculationMethod.egyptian.getParameters();
    params.madhab = Madhab.hanafi;

    final prayerTimes = PrayerTimes(coordinates, date, params);

    expect(DateFormat.jm().format(prayerTimes.fajr), '4:10 AM');
    expect(DateFormat.jm().format(prayerTimes.sunrise), '5:36 AM');
    expect(DateFormat.jm().format(prayerTimes.dhuhr),
        '11:54 AM'); // 11:53 based on Google
    expect(DateFormat.jm().format(prayerTimes.asr),
        '4:24 PM'); // 3:23 based on Google
    expect(DateFormat.jm().format(prayerTimes.maghrib), '6:11 PM');
    expect(DateFormat.jm().format(prayerTimes.isha), '7:27 PM');
  });

Environment

• Dart Language Version: 3.3.3
• Flutter Version: 3.19.5
• Adhan-Dart Version: ^2.0.0+1

CalculationMethod.egyptian fajrAngle is 20.0 and ishaAngle is 18.0 but they should be 19.5 and 17.5 instead.

Make the readme better by adding a section that talks about testing 🧪 . It will tell everyone how to test the package and what rules to follow. This will help us test better and make our software nicer. 🚀

time prayer not show,.
only text waiting for your location.

Is there anyway to obtain the 'sunset' time ?

I have a question about Isha prayer exactly after Isha prayer. So once Isha is done I'm getting a none enum case and I want to show Fajr for the next day.. I tried with:

void _getPrayersForTomorrow() { var newDate = new DateTime(nextPrayerTime.value.year, nextPrayerTime.value.month, nextPrayerTime.value.day + 1); nextPrayer.value = prayerTimes.value.nextPrayerByDateTime(newDate); }

but I still get none as praying time... is there any workaround to archive that?

Hello @iamriajul , this package is outdated. can you please update it to be compatible with Dart 3 and null safety

I noticed that the adhan-dart is giving plus 1hr for Asr time. For example I was expecting to give 17:15 instead of 18:15.
Do you know why?

final params = CalculationMethod.karachi.getParameters();
params.madhab = Madhab.hanafi;
prayerTimes = PrayerTimes.today(myCoordinates, params, utcOffset: _dateTime.timeZoneOffset);

Question related to which version: 2.0.0-nullsafety.2

Description

Is there any method that returns the remaining time to the next prayer? Looking at the documentation, I only see that I can get the current date but nothing else.

What do you think of this article that says fixed degree around the year is not correct in places with high latitudes and low latitudes.
see the link below:

Salam brother..
thanks for developing this package..

I have this error when running the example even though the pray time is generated.

Hope you can address this issue.

E/flutter (29148): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: setState() called after dispose(): _TodayKuliahMasjidWaktuSolatPageState#fe309(lifecycle state: defunct, not mounted) E/flutter (29148): This error happens if you call setState() on a State object for a widget that no longer appears in the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error can occur when code calls setState() from a timer or an animation callback. E/flutter (29148): The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree. E/flutter (29148): This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks, consider breaking the reference to this object during dispose().

For example in pakistan's almost every city is giving correct adhan time while in istanbul or some other location its time is one hour earlier than original. why?

please make response string because im so confuse how to parse prayerTimes to fajr,sunrise or maghrib

Salam Alaykum.
when I enter the app with the location service disable, I get a dialog to allow the service, when I tap ok it is not updating the screen and keeps saying "Waiting for Your Location..." !!!

Describe the bug
Prayer times with the Muslim World League parameters appear to be incorrect.

To Reproduce
Steps to reproduce the behavior:
Create a PrayerTimes object with coordinates (51.5074, 0.1278) [The coordinates of London] and DateComponents(2021, 5, 26), and the Muslim World League parameters, like so:
PrayerTimes( Coordinates(51.5074, 0.1278), DateComponents(2021, 5, 26), CalculationMethod.muslim_world_league.getParameters(), )
Then print out the DateTime objects for Fajr and Isha, and you'll end up with the following:
flutter: 2021-05-26 00:57:00.000 flutter: 2021-05-27 00:31:00.000

Expected behavior
These prayer times are incorrect, and according to IslamicFinder.org with the same coordinates and calculation method, the following should be output instead:

Environment(please complete the following information):

• Dart Language Version: 2.12.0
• Flutter Version: 2.0.1
• Adhan-Dart Version: 1.1.15

Perhaps there is a way to alleviate this issue/a setting that I have not been using, in which case I apologise. Jazakallah for developing this package and may Allah reward you!

Question related to which version: common

Description

I read docs but can't find about it. I do not have detailed information about calculating adhan times. I tried in Turkey with muslim_world_league method its giving wrong times. Can i automize the calculation parameters based on location?
e.g
location is Turkey use CalculationMethod.Turkey
location is NA use CalculationMethod.north_america.
location is kuwait use CalculationMethud.kuwait

Thanks for help.

Midnight calculation should be from Isha (end of sun light) to Fajr (beginning of sun light) / 2 not from Maghrib to Fajr / 2.
I hope this help developer in the next update.

Always getting output

I/flutter (15669): Next Prayer Prayer.maghrib
I/flutter (15669): Current Prayer Prayer.asr

with

    Prayer nextPrayerTimes = prayerTimes.nextPrayer();
    print("Next Prayer $nextPrayerTimes");

    Prayer currentPrayer = prayerTimes.currentPrayer();
    print("Current Prayer $currentPrayer");

At the address below, the Diyanet's prayer times for Istanbul are shown:
https://namazvakitleri.diyanet.gov.tr/en-US/9541/prayer-time-for-istanbul

All prayer times are calculated correctly. But the asr is wrong. How can I solve this problem?

Here is the code I use to get Prayer Times:

print('My Prayer Times');
   final myCoordinates = Coordinates(41.015137, 28.979530); // Istanbul
   final params = CalculationMethod.turkey.getParameters();
   params.madhab = Madhab.hanafi;

   final prayerTimes = PrayerTimes.today(myCoordinates, params);

   print(
       "---Today's Prayer Times in Your Local Timezone(${prayerTimes.fajr.timeZoneName})---");
   print(DateFormat.jm().format(prayerTimes.fajr));
   print(DateFormat.jm().format(prayerTimes.sunrise));
   print(DateFormat.jm().format(prayerTimes.dhuhr));
   print(DateFormat.jm().format(prayerTimes.asr)); // -> Asr time is calculated incorrectly
   print(DateFormat.jm().format(prayerTimes.maghrib));
   print(DateFormat.jm().format(prayerTimes.isha));

   print('---');

dear authors , I am new at flutter and i want to make an app for namaz timing and your api is perfect for me and i want to know that how i can program your api that api automatically detect coordinates based on device location and give results hope you will soon answer my question

Hello Brother.

There are issues with current preyer and next prayer , if you can pleas check and fix.

The issues are as follows:

1- if the current preayer is showing as (Prayer.isha) then the next Prayer is showing (Prayer.none). it should show (Prayer.fajr).

2- if the time is now is after the Sunrise time, it shows (Prayer.sunrise). there is not prayer as sunrise.

Also I have some suggestion to add more time calculations as follows:

1- can you please add (next prayer) is after ....... (count down time)

2- can you please add the time of mid-night (calculated as the mean time from sunset to fajr)

3- can you please add the start time of the last third of the night.
(duration between sunset and fajr / 3 = i) (i + i + sunset time = start time of the last third of the night)

it will better to add Ishraq, Chast Prayer Time

Currently, when I use CalculationMethod.muslim_world_league or other, the adhan time is different.

May there be peace upon you.

The adhan-dart is very cheering, empowering, and an excellent means to serve the nation. I am glad and thankful to Allah that I came across the package. And I would like to cheer up the team who worked on it!

I am having trouble setting up the adhan-dart.

So, What I have done:

1. in the main. dart I am using the widget PrayerTimings()
2. I created another file named, prayer.dart where the main prayer timing widget is placed.

I am posting down my main.dart and prayer.dart file with the errors.
I will feel elevated to be helped.

Assalam 3alaykom,
First of all, thanks for this nice package, it works like a charm and the documentation is really nice.

While implementing your package in my app, I noticed the calculation method of Tehran wasn't available, so I tried to implement the CalculationParameters myself, but I realised that the maghribAngle wasn't implemented in this Dart.

Would it be possible to implement it inshaAllah ?
Here's the JS version: https://github.com/batoulapps/adhan-js/blob/master/src/CalculationParameters.js

Many thanks!

    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,

Hello Brother

I just noticed that highLatitudeRule does not work, i.e when I change to different rules (middle_of_the_night, seventh_of_the_night & twilight_angle) nothing changes in the prayer times of fajr and isha.

can you please clarify this?

Hello brother

Does this package adjust prayer times with regard to summer time variation?
