title: Flutter: knowing if the front camera is mirroring the image
body: <p>I'm implementing live face detection feature in a Flutter app, the problem is that the front camera is mirroring the image in some phone types while the others not</p>
  
  <p>it's easy to mirror the marking rectangle too, but I can't determine if mirroring takes place or not</p>
  
  <p>Isn't there a programmatic way to detect mirroring, or to prevent it?</p>
