title: How to play two sounds at the same time?
body: <p>I've been trying a few things with sounds in flutter lately . Using audioPlayer plugin.</p>
  
  <p>But I'm facing a wall. I have both a background music, and small sounds effects. 
  The problem is that I can't play both at once. If I play the background music, then the sound effect won't play. And the opposite works too. </p>
  
  <p>Any idea about how to solve that issue ?</p>
