The line's width is designed by the SKPaint.StrokeWidth property. You coud define the width before drawing the line.

I want to draw a line which has only one cap but it will have two

It doesn't support to draw only one round cap directly, try to draw the line twice to achieve the style.

Check the code:

   void OnCanvasViewPaintSurface(object sender, SKPaintSurfaceEventArgs args)  
   {  
       SKImageInfo info = args.Info;  
       SKSurface surface = args.Surface;  
       SKCanvas canvas = surface.Canvas;  
     
       canvas.Clear();  
     
       SKPaint thickLinePaint = new SKPaint  
       {  
           Style = SKPaintStyle.Stroke,  
           Color = SKColors.Orange,  
           StrokeWidth = 50  
       };  
     
       float y = textPaint.FontSpacing;  
     
       thickLinePaint.StrokeCap = SKStrokeCap.Round;  
       canvas.DrawLine(xLine1, y, 200, y, thickLinePaint);  
     
       thickLinePaint.StrokeCap = SKStrokeCap.Butt;  
       thickLinePaint.Color = SKColors.Red;  
       canvas.DrawLine(200, y, 500, y, thickLinePaint);  
   }
