Find when a page finished loading in xamarin.forms prism

Question

I am trying to create an optimized Event Tracker for my Xamarin.forms prism application. I would like to know whether there is any method to find out when the page load is finished. If someone could help me, please save my time.

You can implement page loading methods for different platforms through custom renderer.

For iOS, override the viewDidLoad method, ViewDidLoad(Called after the controller's view is loaded into memory.)

[assembly:ExportRenderer (typeof(ContentPage), typeof(MyRenderer))]
namespace Demo.iOS
{
    public class MyRenderer : PageRenderer
    {

        protected override void OnElementChanged(VisualElementChangedEventArgs e)
        {
            base.OnElementChanged(e);
        }
        public override void ViewDidLoad()
        {
            base.ViewDidLoad();
        }
    }
}

For Android, rewrite the OnAttachedToWindow method, OnAttachedToWindow(This is called when the view is attached to a window.)

[assembly: ExportRenderer(typeof(ContentPage), typeof(MyRenderer))]
namespace Demo.Droid
{
    public class MyRenderer : PageRenderer
    {
        public MyPageRenderer(Context context) : base(context)
        {
        }

        protected override void OnElementChanged(ElementChangedEventArgs<Page> e)
        {
            base.OnElementChanged(e);
        }

        protected override void OnAttachedToWindow()
        {
            base.OnAttachedToWindow();
        }
    }
}
