Add shadow to a Label - Xamarin.Forms - xaml

Question

I would like to add drop shadow to a Label. This label is overlapped in the Page, like an always visible control that opens a filtering page.
Please find a gif attached with my screen:
Here's my XAML:
<!-- **** Filter button **** -->
<Label
Margin="0,0,10,10"
WidthRequest="50"
HeightRequest="50"
HorizontalOptions="End"
VerticalOptions="End"
HorizontalTextAlignment="Center"
VerticalTextAlignment="Center"
FontSize="30"
Style="{DynamicResource FilterAction}"
Text=""
BackgroundColor="{StaticResource ComplementColor}"
FontFamily="{x:Static artina:FontAwesome.FontName}"
TextColor="White">
<Label.GestureRecognizers>
<TapGestureRecognizer Command="{Binding btn_open_filter_businesses_click}" />
</Label.GestureRecognizers>
</Label>
<templates:Badge
BadgeText="{Binding number_of_filters_selected}"
BadgeTextColor="White"
BadgeBackgroundColor="#1DBDFF"
HorizontalOptions="End"
VerticalOptions="End"
TranslationX="-4"
TranslationY="-4"
IsVisible="{Binding number_of_filters_selected, Converter={StaticResource filterVis}"
x:Name="filtersCountBagde">
<templates:Badge.GestureRecognizers>
<TapGestureRecognizer Command="{Binding btn_open_filter_businesses_click}" />
</templates:Badge.GestureRecognizers>
</templates:Badge>
I would like something like Gmail, find the example below:
Any help would be appreciated.

You can use Xamarin Effects to achieve a shadow on your button. There is a code sample that you can download here which should get you started:
Shadow Effect
It will involve creating platform-specific implementations for your shadow.
You could also try the idea put forward in this similar question.
