Exploring Flutter’s Animation Library
Learn how Flutter’s animation library is built up and understand the fundamentals of it
Flutter offers a robust animation library that enhances the interactivity and visual appeal of apps. This article will take a look at the heart of the animations in Flutter, the animations library. We will take a look at the foundational concepts of the animation library as well as practical applications.
