I created a simple proyect with a flyout, using prism library too...

We put the code to color the navigation bar in red and yellow but no way to have it in Ios simulator... or android app...
In android it appears in blue, and iphone in white...

How can we do it?

thanks

Here is the repro project... TestPrism.zip

Can you maybe explain a bit more about what you have tried and what you think it should do but doesn't work?

Looking at your code the only reference to doing this seems to be in MenuIniziale and it sets the background color of the page? So I'm not 100% sure if I understand what you mean :)

Also, it would really help if you could provide a reproduction project as a public GitHub repo next time, thanks!

Hi, my aim is to put a color to the navigationbar background.

I set all the properties I think I need but in android it appears in blue and in IOS in white......

Here is a repro project https://github.com/AngeloLazzari/NavigationBarColorTest

thanks

I think you should be using the Shell.BackgroundColor:

• https://learn.microsoft.com/dotnet/maui/fundamentals/shell/pages?view=net-maui-8.0#set-page-colors
• https://dev.to/dotnet/exploring-colors-in-xamarin-forms-shell-16g3

Hi, I don't use shell, I use FLyout page and prism navigation.

[mattleibow]

I am not sure I understand what should be having a color... Maybe attach a screenshot and circle/color the part you think should have color.

I see NavigationPage has a BarBackgroundColor... But not sure what should be colored as you don't have any navigation properties set, just the page background.

Hello, as you can see, the same app built in Android looks like this

and the IOS one like this...

but I put the code
BackgroundColor="Red"
Background="Yellow" ... no the purple one showed...

`

<FlyoutPage.Flyout>
    <ContentPage Title="Menu">
        <VerticalStackLayout>
            <Label 
        Text="Menu"
        VerticalOptions="Center" 
        HorizontalOptions="Center" />

            <Button Text="Pagina Iniziale" Command="{Binding ApriPaginaInizizale}" />
            <Button Text="Pagina 2" Command="{Binding ApriPagina2}" />
            <Button Text="Pagina 3" Command="{Binding ApriPagina3}" />
            
        </VerticalStackLayout>
    </ContentPage>
</FlyoutPage.Flyout>

`

thank you very much

The page background is just setting the background of the page, and not of the nav bar.

Now, how to set the nav bar, let me see if @PureWeen knows...

[mattleibow]

I think Prism is hiding the navigation page for you, but you can still get to it via a style:

    <FlyoutPage.Resources>
        <ResourceDictionary>
            <Style TargetType="NavigationPage" ApplyToDerivedTypes="True">
                <Setter Property="BarBackgroundColor" Value="Yellow" />
            </Style>
        </ResourceDictionary>
    </FlyoutPage.Resources>

[mattleibow]

Let me know if that helps.

[AngeloLazzari]

Yes, it worked like a charm!!!! thank you very much.

One more think, now I have to change the title, menu and icones that appear on the navigation bar, i tryed with TextColor, color, titleColor, but no way, can you help me a bit more?

[mattleibow]

I am not sure, but @PureWeen may know.

But, the docs say BarTextColor and IconColor are the things to use. Have you tried those? You may also have to put it in the style since you do not have access to the navigation page directly.

[AngeloLazzari]

yes, all is working with that, thank you very much for the help.
