我需要有一个Xamarin表单按钮(两种不同的大小)格式化的文本

<Button Text="按钮文本" />

<Button Text="按钮文本" FontSize="20" TextColor="Red" FontAttributes="Bold" />

<ContentPage.Resources>
    <ResourceDictionary>
        <Style x:Key="LargeButtonStyle" TargetType="Button">
            <Setter Property="FontSize" Value="24" />
            <Setter Property="HeightRequest" Value="60" />
            <Setter Property="WidthRequest" Value="200" />
        </Style>
        <Style x:Key="SmallButtonStyle" TargetType="Button">
            <Setter Property="FontSize" Value="16" />
            <Setter Property="HeightRequest" Value="40" />
            <Setter Property="WidthRequest" Value="150" />
        </Style>
    </ResourceDictionary>
</ContentPage.Resources>

<Button Text="大按钮" Style="{StaticResource LargeButtonStyle}" />
<Button Text="小按钮" Style="{StaticResource SmallButtonStyle}" />
