In Flutter, it is possible to create some exciting animations quite simply. It might seem slightly roundabout initially, but it is intuitive once you understand what is happening. For example, if you need a fade animation, you can use FadeTransition to create this. You need to have an AnimationController and a CurvedAnimation to build it inside a StatefulWidget with the SingleTickerProviderStateMixin for it to work, but once it is set up it is extendable.
