#Compose Animation Docs

Here is the documentation for animation inCompose, a modern tool for Android UI development. Compose is designed to be intuitive and powerful, allowing developers to create high-performance UIs with less code.

Basics of Animation

Animation in Compose is based on the idea of animated values. These are values that change over time, and they can be used to animate various UI components.

Key Points

• Animated Values: Represent properties that change over time.
• Animation Controller: Manages the animation and updates the animated values.
• Transition: Defines how the animated values transition between states.

Examples

To get started, let's look at a simple example of animating a button's opacity:

val opacity = animateFloatAsState(value = 0f)

Button(onClick = { opacity.value = 1f }) {
    Box(
        modifier = Modifier
            .size(100.dp)
            .fillColor(Color.Red)
            .alpha(opacity.value)
    )
}
