I am coding a kind of chat GUI, so when a entry event is excuted it shoud get the text inside it and set it into a label which then is set into a frame, so that that frame can be stablished in a stacklayout which is previously defined in the .xaml file. The problem is the text is gotten but the frame with the given text never appears on screen

i tried this

private void Entry_Completed(object sender, EventArgs e){
  
   string text = Entrada.Text;

   
   var rectangle = new Frame
   {
      
       Content = new Label
       {
         Text = text,
         FontAttributes = FontAttributes.Bold,
         VerticalTextAlignment = TextAlignment.Center,
         HorizontalTextAlignment = TextAlignment.Center,
         FontAutoScalingEnabled = true,
         TextColor = Color.FromArgb("ffffff"),

   },
        MaximumHeightRequest = layout2.WidthRequest / 2,
        HorizontalOptions = LayoutOptions.End,
        BackgroundColor = Color.FromArgb("#1D438A"),
  };

   Entry.Text = "";
   layout2.Children.Add(rectangulo);
}
