Documentation for Maui Shell Flyout has typecast errors in Android when using the default template provided with AppThemeBinding

[biozal]

Type of issue

Code doesn't work

Description

When using the default template for Flyout Items provided here: https://learn.microsoft.com/en-us/dotnet/maui/fundamentals/shell/flyout?view=net-maui-8.0#default-template-for-flyoutitems

Specifically this code below:

<Label.TextColor>
                <OnPlatform x:TypeArguments="Color">
                    <OnPlatform.Platforms>
                        <On Platform="Android"
                            Value="{AppThemeBinding Light=Black, Dark=White}" />
                    </OnPlatform.Platforms>
                </OnPlatform>
            </Label.TextColor>

The App will crash on Android with API 31 and higher (tested on API 31, 32, and 33). I haven't tested in prior versions. It seems there are issues with Maui, Shell, and the Flyout navigation menu and the docs aren't helping because I can't get a Flyout menu to stabile work with the set documentation provided in this page.

I have also raised an issue with the background color not working on the Maui board which when used with this documentation code the bug worse: https://github.com/dotnet/maui/issues/19141

Also in iOS there is an issue with the header code provided that it causes the first link in iOS in the Flyout menu to to not work: https://github.com/dotnet/maui/issues/17965
