title: How to make carousel/slider/image switcher with fading effect in Flutter
body: <p>I found many online slider libraries like the one here: <a href="https://github.com/GeekyAnts/flutter-carousel" rel="nofollow noreferrer">https://github.com/GeekyAnts/flutter-carousel</a>
  But none of them supports fading effect between images (image transition between slides to be fading). </p>
  
  <p>I found also an example of fading animated widgets in the documentation here: <a href="https://api.flutter.dev/flutter/widgets/AnimatedCrossFade-class.html" rel="nofollow noreferrer">https://api.flutter.dev/flutter/widgets/AnimatedCrossFade-class.html</a>
  and
  <a href="https://api.flutter.dev/flutter/widgets/AnimatedSwitcher-class.html" rel="nofollow noreferrer">https://api.flutter.dev/flutter/widgets/AnimatedSwitcher-class.html</a></p>
  
  <p>I'm thinking about make placeholder widget and using a timer to switch between image using the suggested approach in the documentation. Is this the best approach to achieve that? Are there any other ready-made libraries or easier way to do it?</p>
