toast that wait for an exist toast to disapear

Hi,

My problem is that I created a toast that works fine, but unfortunately, toasts are not very polite, and don't not wait until the current shown toast will
finish its job. It just moves it away.
I can solve it in an ugly way, which means to put Task.Delay() before the second toast (in order to let the first toast to finish its job).

I wondered if there is a better way.

This is how I created the toast.
1. I created an interface in Xamarin Forms:
public interface IMessage
{
void LongAlert(string message);
void ShortAlert(string message);
}

2. In Android Project I wrote the implementation:

   public class MessageAndroid : IMessage
   {
   public void LongAlert(string message)
   {
   Toast.MakeText(Application.Context,message, ToastLength.Long).Show();
   }

       public void ShortAlert(string message)
       {
           Toast.MakeText(Application.Context, message, ToastLength.Short).Show();
       }
   

   }
