[BUG] Back button is not visible on the navigation bar in light mode

[RsZoli]

Description

After navigating from a page, the back button is not visible (or presumably just white) if the device is in light mode! The bug is present on Android and iOS platforms as well, but the navigation itself is working!

In dark mode, the back button is visible!

Steps to Reproduce

Create a new .NET MAUI application and navigate from the MainPage.

Same issue here. Can't change the color of my custom back icon from white to anything else.

This bug has been fixed by https://github.com/dotnet/maui/pull/20152. The fix will be automatically present in newly created MAUI projects. To integrate it into an existing project, replace the existing Shell.ForegroundColor property in Resources\Styles\Styles.xaml with the following:

<Setter Property="Shell.ForegroundColor" Value="{AppThemeBinding Light={StaticResource Black}, Dark={StaticResource SecondaryDarkText}}" />
