## Cleveroad introduces Sliding Tutorial Library for Flutter

65
Hey guys, hope you haven’t started developing a tutorial for your Flutter app yet, as we have already completed a part of your job. Don’t worry, we act from good motives only. Our aim is to help you create a sliding tutorial in a fast and simple manner. So we’ve done some work and voila!. A simple Flutter Sliding Tutorial library is at your service.

###### Also you can watch the animation of the <strong><a target="_blank" href="https://www.youtube.com/watch?v=lJSGIk4Zh9s&feature=youtu.be">Sliding Tutorial for Android on YouTube</a></strong> in HD quality.

The invention is going to ease the problem of structural design but not to limit a stretch of your imagination at the same time. We took care of the suitability aspect. So, your app is not going to look alien among other Flutter elements.
