The color of hamburger icon in FlyoutPage changed to the white in Maui.

Question

My project is using FlyputPage as follows:

<FlyoutPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
            xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            xmlns:local="clr-namespace:FlyoutPageNavigation"
            x:Class="FlyoutPageNavigation.MainPage">
    <FlyoutPage.Flyout>
        <local:FlyoutMenuPage x:Name="flyoutPage" />
    </FlyoutPage.Flyout>
    <FlyoutPage.Detail>
        <NavigationPage>
            <x:Arguments>
                <local:ContactsPage />
            </x:Arguments>
        </NavigationPage>
    </FlyoutPage.Detail>
</FlyoutPage>

You could see that I set a hamburger.png icon in FlyoutMenuPage:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:FlyoutPageNavigation"
             x:Class="FlyoutPageNavigation.FlyoutMenuPage"
             Padding="0,40,0,0"
             IconImageSource="hamburger.png"
             Title="Personal Organiser">
 //...
                    x:FieldModifier="public"
                    SelectionMode="Single">
        <CollectionView.ItemsSource>
            <x:Array Type="{x:Type local:FlyoutPageItem}">
                <local:FlyoutPageItem Title="Contacts"
                                      IconSource="contacts.png"
                                      TargetType="{x:Type local:ContactsPage}" />
                <local:FlyoutPageItem Title="TodoList"
                                      IconSource="todo.png"
                                      TargetType="{x:Type local:TodoListPage}" />
                <local:FlyoutPageItem Title="Reminders"
                                      IconSource="reminders.png"
                                      TargetType="{x:Type local:ReminderPage}" />
            </x:Array>
        </CollectionView.ItemsSource>
        <CollectionView.ItemTemplate>
            <DataTemplate>
                <Grid Padding="5,10">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="30"/>
                        <ColumnDefinition Width="*" />
                    </Grid.ColumnDefinitions>
                    <Image Source="{Binding IconSource}" />
                    <Label Grid.Column="1"
                           Margin="20,0"
                           Text="{Binding Title}"
                           FontSize="20"
                           FontAttributes="Bold"
                           VerticalOptions="Center" />
                </Grid>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>
</ContentPage>

The origin color of hamburger icon is blue, however it always show white when program is running.

Maybe it's a bug of Maui, we need to find a solution to solve this.

Note: We are using .net 7.0 with Visual Studio Community 2022 for Mac Version 17.6.12 (build 410), and running it in iOS 17.3 devices.

Thanks for taking care of this problem in advance.

Hello,

The FlyoutPage.Detail is a NavigationPage , the color of hamburger icon is influenced by the BarTextColor of NavigationPage . Please open the Styles.xaml file under Resources/Styles folder, then modify the BarTextColor of NavigationPage.

For example:

<Style TargetType="NavigationPage">
...
<Setter Property="BarTextColor" Value="{AppThemeBinding Light={StaticResource Blue100Accent}, Dark={StaticResource White}}" />

</Style>

Note: .NET7 is not supported, please update your project to .NET8

Best Regards,

Wenyan Zhang
