title: How to immediately replace the current toast with a second one without waiting for the current one to finish?
body: <p>I have many buttons. And on click of each of them I show a Toast. But while a toast loads and show in view, another button is clicked and the toast is not displayed until the one that is being displayed finishes.</p>
  
  <p>So, I would like to sort out a way to detect if a toast is showing in the current context. Is there a way to know if a toast is being displayed such that I can cancel it and display a new one.</p>
