My question is an extension to this question where I want to change the text color based on the state of the radio button. I want it white if checked and black if unchecked.

Details:
I am using a custom styled Radio Button in my application following Redefine RadioButton appearance where it creates ControlTemplate to customize the appearance and uses ContentPresenter for displaying text/content.

I modified it to the shape I want, but unable to change the Text color based on the whether the radio button is checked or not.

Below is my code.

<ControlTemplate x:Key="RadioButtonTemplate">
    <Border x:Name="RadioBorder1"
            StrokeShape="RoundRectangle 3"
            BackgroundColor="#F3F2F1"
            HeightRequest="30"
            WidthRequest="120">
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroupList>
                <VisualStateGroup x:Name="CheckedStates">
                    <VisualState x:Name="Checked">
                        <VisualState.Setters>
                            <Setter Property="BackgroundColor" Value="MediumPurple" />
                            <Setter Property="Stroke" Value="MediumPurple" />
                            <Setter TargetName="check" Property="Opacity" Value="1" />
                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="Unchecked">
                        <VisualState.Setters>
                            <Setter Property="BackgroundColor" Value="#F3F2F1" />
                            <Setter Property="Stroke" Value="#F3F2F1" />
                            <Setter TargetName="check" Property="Opacity" Value="0" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateGroupList>
        </VisualStateManager.VisualStateGroups>
        <Grid Margin="4" WidthRequest="120">
            <Grid WidthRequest="120" HeightRequest="30">
                <RoundRectangle />
                <RoundRectangle x:Name="check" />
            </Grid>
            <ContentPresenter HorizontalOptions="StartAndExpand" Padding="5,1,1,1" />
        </Grid>
    </Border>
</ControlTemplate>

<Style TargetType="RadioButton">
            <Setter Property="ControlTemplate"
                    Value="{StaticResource RadioButtonTemplate}" />
</Style>

And this is what I have now. and I am trying to change the text color to white for the selected item.

Thanks for your help.
