Is there a way that I can use Spans inside of a label and also have it justified?

Question

I am using this code to add some colors to my text inside of a label:

You will have to update the renderer to consider FormattedText. For e.g.: try changing renderer logic to following:

public class JustifiedLabelRenderer : LabelRenderer
{
    protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
    {
        base.OnElementChanged(e);

        //if we have a new forms element, update text
        if (e.NewElement != null)
            UpdateTextOnControl();
    }

    protected override void OnElementPropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
    {
        base.OnElementPropertyChanged(sender, e);

        //if there is change in formatted-text, trigger update to redraw control
        if (e.PropertyName == nameof(Label.FormattedText))
        {
            UpdateTextOnControl();
        }
    }

    void UpdateTextOnControl()
    {
        if (Control == null)
            return;

        //define paragraph-style
        var style = new NSMutableParagraphStyle()
        {
            Alignment = UITextAlignment.Justified,
            FirstLineHeadIndent = 0.001f,

        };

        //define frame to ensure justify alignment is applied
        Control.Frame = new RectangleF(0, 0, (float)Element.Width, (float)Element.Height);
        Control.Lines = 0;

        if (Element.FormattedText.ToAttributed(Element.Font, Element.TextColor) is NSMutableAttributedString attrText)
        {
            var fullRange = new NSRange(0, attrText.Length);
            attrText.AddAttribute(UIStringAttributeKey.ParagraphStyle, style, fullRange);
            Control.AttributedText = attrText;
        }
    }
}
