xamarin.forms - Xamarin Forms Flyout 菜单底部选项卡样式

Question

我的应用程序中有以下 Shell Flyout 菜单：

<?xml version="1.0" encoding="utf-8" ?>
<Shell xmlns="http://xamarin.com/schemas/2014/forms"
   xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
   xmlns:views="clr-namespace:UniversalCheckInApp.Views"
   x:Class="UniversalCheckInApp.AppShell">

<Shell.FlyoutHeader>
    <StackLayout BackgroundColor="#1E1F26" Padding="4,4,4,4">
        <Label Text="Navigation" TextColor="#D0E1F9" FontAttributes="Bold" HorizontalTextAlignment="Start"
               VerticalTextAlignment="Center" FontSize="Large" Margin="4,4,4,4" />
    </StackLayout>
</Shell.FlyoutHeader>


<Shell.ItemTemplate>
    <DataTemplate>
        <StackLayout HorizontalOptions="StartAndExpand" Padding="16,0,4,0" >
            <Label Text="{Binding Title}" TextColor="#1E1F26" VerticalOptions="Center" 
                   HorizontalOptions="Start" Margin="0,0,0,0" FontSize="Medium" FontAttributes="Bold" 
                   TextDecorations="Underline"/>
        </StackLayout>
    </DataTemplate>
</Shell.ItemTemplate>

<FlyoutItem Title="Configuration" >
    <ShellContent x:Name="scNetworkConfiguration" Title="Network Configuration" >
        <views:NetworkConfiguration />
    </ShellContent>

    <ShellContent x:Name="scDataConfiguration" Title="Data Configuration">
        <views:FormFieldConfiguration />
    </ShellContent>
</FlyoutItem>

<FlyoutItem Title="Collect Data">
    <ShellContent x:Name="scCollectData" Title="Collect Data">
        <views:DataCollection />
    </ShellContent>
</FlyoutItem>


<FlyoutItem Title="About">
    <ShellContent x:Name="scAbout" Title="About">
        <views:About />
    </ShellContent>
</FlyoutItem>

它呈现如下：

我试图弄清楚如何更改出现在每个配置页面底部的两个菜单选项的样式。

更新

根据下面的评论，我能够在底部获得弹出菜单选项，如下所示：

使用此 XAML

<?xml version="1.0" encoding="utf-8" ?>
<Shell xmlns="http://xamarin.com/schemas/2014/forms"
   xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
   xmlns:views="clr-namespace:UniversalCheckInApp.Views"
   x:Class="UniversalCheckInApp.AppShell"
   FlyoutBackgroundColor="#D0E1F9"
   BackgroundColor="#1E1F26"
   Shell.TabBarBackgroundColor="#1E1F26"
   Shell.TabBarTitleColor="#D0E1F9"
   Shell.TabBarUnselectedColor="White">


<Shell.FlyoutHeader>
    <StackLayout BackgroundColor="#1E1F26" Padding="4,4,4,4">
        <Label Text="Navigation" TextColor="#D0E1F9" FontAttributes="Bold" HorizontalTextAlignment="Start"
           VerticalTextAlignment="Center" FontSize="Large" Margin="4,4,4,4" />
    </StackLayout>
</Shell.FlyoutHeader>


<Shell.ItemTemplate>
    <DataTemplate>
        <StackLayout HorizontalOptions="StartAndExpand" Padding="16,0,4,0" >
            <Label Text="{Binding Title}" TextColor="#1E1F26" VerticalOptions="Center" 
               HorizontalOptions="Start" Margin="0,0,0,0" FontSize="Medium" FontAttributes="Bold" 
               TextDecorations="Underline"/>
        </StackLayout>
    </DataTemplate>
</Shell.ItemTemplate>

<FlyoutItem Title="Configuration" >
    <ShellContent x:Name="scNetworkConfiguration" Title="Network Configuration" >
        <views:NetworkConfiguration />
    </ShellContent>

    <ShellContent x:Name="scDataConfiguration" Title="Data Configuration">
        <views:FormFieldConfiguration />
    </ShellContent>
</FlyoutItem>

<FlyoutItem Title="Collect Data">
    <ShellContent x:Name="scCollectData" Title="Collect Data">
        <views:DataCollection />
    </ShellContent>
</FlyoutItem>


<FlyoutItem Title="About">
    <ShellContent x:Name="scAbout" Title="About">
        <views:About />
    </ShellContent>
</FlyoutItem>

现在的挑战是我想调整选项卡栏选定和未选定项目的 FontSize、FontAttributes 和 TextDecorations 属性。知道怎么做吗？
