Compose Animation Core

Jetpack Compose API reference for animation-core.

  • Animatable

    This Animatable function creates a float value holder that automatically animates its value when the value is changed via animateTo.

  • animate

    Target based animation that animates from the given initialValue towards the targetValue, with an optional initialVelocity.

  • animateDecay

    Decay animation that slows down from the given initialVelocity starting at initialValue until the velocity reaches 0.

  • animateTo

    Target based animation that takes the value and velocity from the AnimationState as the starting condition, and animate to the targetValue, using the animationSpec.

  • AnimationState

    Factory method for creating an AnimationState for Float initialValue.

  • AnimationVector

    Factory method to create an AnimationVector1D

  • calculateTargetValue

    Calculates the target value of a decay animation based on the initialValue and initialVelocity, and the typeConverter that converts the given type T to AnimationVector.

  • copy

    Creates a new AnimationState from a given AnimationState.

  • createZeroVectorFrom

    Creates an AnimationVector with all the values set to 0 using the provided TwoWayConverter and the value.

  • DecayAnimation

    DecayAnimation is an animation that slows down from initialVelocity as time goes on.

  • exponentialDecay

    Creates a decay animation spec where the friction/deceleration is always proportional to the velocity.

  • generateDecayAnimationSpec

    Creates a DecayAnimationSpec from a FloatDecayAnimationSpec by applying the given FloatDecayAnimationSpec on every dimension of the AnimationVector that T converts to.

  • getVelocityFromNanos

    Returns the velocity of the animation at the given play time.

  • infiniteRepeatable

    Creates a InfiniteRepeatableSpec that plays a DurationBasedAnimationSpec (e.

  • keyframes

    Creates a KeyframesSpec animation, initialized with init.

  • keyframesWithSpline

    Creates a KeyframesWithSplineSpec animation, initialized with init.

  • repeatable

    Creates a RepeatableSpec that plays a DurationBasedAnimationSpec (e.

  • snap

    Creates a Snap animation for immediately switching the animating value to the end value.

  • spring

    Creates a SpringSpec that uses the given spring constants (i.

  • TargetBasedAnimation

    Creates a TargetBasedAnimation with the given start/end conditions of the animation, and the provided animationSpec.

  • tween

    Creates a TweenSpec configured with the given duration, delay and easing curve.

  • TwoWayConverter

    Factory method to create a TwoWayConverter that converts a type T from and to an AnimationVector type.

  • withInfiniteAnimationFrameMillis

    Like withFrameMillis, but applies the InfiniteAnimationPolicy from the calling CoroutineContext if there is one.

  • withInfiniteAnimationFrameNanos

    Like withFrameNanos, but applies the InfiniteAnimationPolicy from the calling CoroutineContext if there is one.
