Xamarin.forms: [Arabic] Hijri date shown on DatePicker while the popup selector shows Gregorian dates

[primehalo]

Description

When the app's culture is set to Arabic the date shown on a DatePicker is in the Hijri calendar rather than the Gregorian calendar despite Gregorian dates being shown when the DatePicker is actually opened. There is seemingly no way to force the DatePicker to show the Gregorian date. My workaround was go make a custom DatePicker so I could change Control.Text = date.ToString(Element.Format) to Control.Text = date.ToString(Element.Format, new System.Globalization.CultureInfo("en")). It'd be really nice if we could just set the culture of the DatePicker.

Steps to Reproduce

1. Set the culture to Arabic
2. Add a DatePicker to a page
3. The date in the DatePicker will show as Hijri
4. Tap on the DatePicker and see a Gregorian calendar in Android or a Picker of Gregorian dates in iOS.

Expected Behavior

I would expect the date shown in the date picker to match the dates shown when the picker is open.

Actual Behavior

The DatePicker shows a Hijri date but Gregorian dates are shown when presented with the dates to pick from.

It may be that we need to correctly set the locale or calendar for the UIDatePicker.

"Specified time is not supported in this calendar. It should be between 04/30/1900 00:00:00 (Gregorian date) and 11/16/2077 23:59:59 (Gregorian date), inclusive.\nParameter name: time"

I haven't attempted to use the datepicker since I wrote my workaround which was over a couple years ago so I have no idea if it has been fixed yet.
