  Label has a property TextDecorations where you can set strikethrough text. For effects you need to make sure that using of them is right. Check in documentation how to properly use effects.

  Also I can't see a link between trigger and Style.
  Maybe its better to bind TextDecorations property of Label to property of ViewModel? And when your operation is changing just call OnPropertyChanged for that property?

  Thank you. However, I do not believe TextDecorations are in the version of Xamarin.Forms I am using (3.2.x).

  You can use TextDecorations property in the version of Xamarin.Forms(3.3.x).

  There are to ways to consume the effect :
  in xaml

  <Entry Text="Effect attached to an Entry" ...>
      <Entry.Effects>
          <local:FocusEffect />
      </Entry.Effects>
      ...
  </Entry>
  

  in c#

  public HomePageCS ()
  {
    ...
    entry.Effects.Add (Effect.Resolve ($"MyCompany.{nameof(FocusEffect)}"));
    ...
  }

  I've reproduced the code. There are no 'Effects' in Setter's Property.
  You can change the code as follows :

  <?xml version="1.0" encoding="UTF-8"?>
  <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:EffectsDemo" x:Class="EffectsDemo.HomePage">
      <StackLayout Padding="0,20,0,0">
          <Label Text="Effects Demo - Focus Effect" FontAttributes="Bold" HorizontalOptions="Center">
              <Label.Effects>
                  <local:FocusEffect />
              </Label.Effects>
      ...
              <Label.Triggers>
                  <DataTrigger TargetType="Label"
                               Value="2">
                      <Setter Property="FontSize">
                          <Setter.Value>
                              24
                          </Setter.Value>
                      </Setter>
                  </DataTrigger>
              </Label.Triggers>
          </Label>
      </StackLayout>
  </ContentPage>
