纬度大于65:错误值不应该是无限或NaN，使用adhan包

Question

纬度值介于(-67.5944046和-90)和(65.9277379和90)之间抛出未处理异常!

产生错误的最小代码:

import 'package:adhan/adhan.dart';
void main() {
//latitude values between (-67.5944046 and -90) and between (65.9277379 and 90)
//throw Unhandled exception!
// var prayerTimes = PrayerTimes(Coordinates(-67.5944046, 120),
// DateComponents.from(DateTime.now()), CalculationMethod.umm_al_qura.getParameters());
var prayerTimes = PrayerTimes(Coordinates(65.9277379, 120),
DateComponents.from(DateTime.now()), CalculationMethod.umm_al_qura.getParameters());
print(prayerTimes.fajr);
}

预期行为应输出给定参数的实际祈祷时间。

但是会抛出错误:

C:/Flutter_SDK/flutter/bin/cache/dart-sdk/bin/dart.exe --enable-asserts "E:Flutter_UIhij_greg_temp - Copylibmain.dart"

adhan - dart Version: [adhan: ^2.0.0-nullsafety.2]

注意:以前的版本(adhan: ^1.1.14)工作得很好，但我不能再使用它了，因为它不提供nullsafety。

Answer 1

尝试使用验证参数设置为false，就像这样

var prayerTimes = PrayerTimes(Coordinates(65.9277379, 120, validate: false),
DateComponents.from(DateTime.now()), CalculationMethod.umm_al_qura.getParameters());

或者从repo中提取源代码，自己在库代码中添加null安全，然后给出合并请求。一旦开发人员接受，您就可以毫无问题地使用它了。
