title: kivy python flashing text
body: <p>I would like to display flashing text (every 1 sec.) in my kivy app. I have searched through google but can not find any examples / information about it.</p>
  
  <p>is it possible to do flashing text (label) in kivy at all?</p>
  
  <p>EDIT:</p>
  
  <p>The way I have done it is that I call a Clock to call a specific function every second to update screen.</p>
  
  <p>I have defined global variable cnt as well and within above mentioned function I use if statements:</p>
  
  <pre><code>if cnt == 1:
      screen.ids.mynumber.text = 'STAND CLEAR'
  if cnt == -1:
      screen.ids.mynumber.text = ''
  cnt = - cnt
  </code></pre>
  
  <p>In this way I change cnt value every second to -cnt and either display text or not. any better way to do it in kivy?</p>
