Animations in Flutter

Welcome to the Animations in Flutter guide! In this section, we'll explore animation concepts and how to implement them in Flutter.

Overview of Animations in Flutter

Animations add life and interactivity to your Flutter apps. Flutter provides a rich set of tools for creating smooth and engaging animations.

Animation Controllers

The AnimationController class is used to control animations. It allows you to define the animation duration, start, stop, and reverse animations.

AnimationController controller = AnimationController(
  duration: Duration(seconds: 2),
  vsync: this, // TickerProvider
);

Animation<double> animation = Tween<double>(begin: 0, end: 1).animate(controller);

Tweens and Curves

Tween objects define the range of values for an animation, and Curves define the rate of change of an animation.

Animation<double> animation = Tween<double>(begin: 0, end: 1).animate(controller);

// Applying a curve
animation = CurvedAnimation(parent: controller, curve: Curves.easeInOut);

Examples of Common Animations

Fade Animation

FadeTransition(
  opacity: animation,
  child: YourWidget(),
)

Slide Animation

SlideTransition(
  position: Tween<Offset>(begin: Offset(-1, 0), end: Offset(0, 0)).animate(controller),
  child: YourWidget(),
)
