Visualize gradient on a line at runtime

I'm trying to create a Tline Shape at runtime and assign a gradient without success. When creating other shapes such as circles or squares, no problem appears.

Note: At design time, a Tline shape does the gradient. I'm using Tokyo version 10.2

unit Unit1;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.Objects;

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.fmx}

procedure TForm1.FormCreate (Sender: TObject);
var
  DLine     : TLine;
begin
  DLine := Tline.Create (nil);
  DLine.Position.x := 100;
  DLine.Position.y := 100;
  DLine.Height := 300;
  DLine.LineType := TLineType.Left;
  DLine.Stroke.Thickness := 3;
  DLine.Fill.Gradient.Color :=   $FF0000FF; // Blue
  DLine.Fill.Gradient.Color1 :=  $FFFF7F50; // Coral
  DLine.Fill.Kind := TBrushKind.Gradient;
  DLine.Fill.Gradient.Style := TGradientStyle.Linear;
  DLine.Parent := Form1;
end;

end.

enter image description here Use DLine.Stroke instead of DLine.Fill

  ...   
  DLine.Stroke.Thickness := 3;
  DLine.Stroke.Gradient.Color :=   $FF0000FF; // Blue
  DLine.Stroke.Gradient.Color1 :=  $FFFF7F50; // Coral
  DLine.Stroke.Kind := TBrushKind.Gradient;
  DLine.Stroke.Gradient.Style := TGradientStyle.Linear;
  ...
