One of the most essential components that make users experience far more interesting to a new level and provide rich user interaction.

What is Animation?

In Flutter, an Animation object knows nothing about what is onscreen. An Animation is an abstract class that understands its current value and its state (completed or dismissed). One of the more commonly used animation types is Animation<double>.

How it works

  • An Animation object sequentially generates interpolated numbers between two values over a certain duration. The output of an Animation object might be linear, a curve, a step function, or any other mapping you can devise. Depending on how the Animation object is controlled, it could run in reverse, or even switch directions in the middle.
  • Animations can also interpolate types other than double, such as Animation<Color> or Animation<Size>.
  • An Animation object has state. Its current value is always available to the .value member.
  • An Animation object knows nothing about rendering or build() functions.

What you’ll learn

  • How to use the fundamental classes from the animation library to add animation to a widget.
  • When to use AnimatedWidget vs. AnimatedBuilder.
  • StatusListeners to monitor animation.
  • Easing animation
  • Tween Animation Builder.
