Methods #

static decay(value, config) #

Animates a value from an initial velocity to zero based on a decay -coefficient.

Config is an object that may have the following options:

  • velocity: Initial velocity. Required.
  • deceleration: Rate of decay. Default 0.997.
  • useNativeDriver: Uses the native driver when true. Default false.

static timing(value, config) #

Animates a value along a timed easing curve. The +coefficient.

Config is an object that may have the following options:

  • velocity: Initial velocity. Required.
  • deceleration: Rate of decay. Default 0.997.
  • isInteraction: Whether or not this animation creates an "interaction handle" on the +InteractionManager. Default true.
  • useNativeDriver: Uses the native driver when true. Default false.

static timing(value, config) #

Animates a value along a timed easing curve. The Easing module has tons of predefined curves, or you can use your own function.

Config is an object that may have the following options:

  • duration: Length of animation (milliseconds). Default 500.
  • easing: Easing function to define curve. -Default is Easing.inOut(Easing.ease).
  • delay: Start the animation after delay (milliseconds). Default 0.
  • useNativeDriver: Uses the native driver when true. Default false.

static spring(value, config) #

Spring animation based on Rebound and -Origami. Tracks velocity state to -create fluid motions as the toValue updates, and can be chained together.

Config is an object that may have the following options. Note that you can -only define bounciness/speed or tension/friction but not both:

  • friction: Controls "bounciness"/overshoot. Default 7.
  • tension: Controls speed. Default 40.
  • speed: Controls speed of the animation. Default 12.
  • bounciness: Controls bounciness. Default 8.
  • useNativeDriver: Uses the native driver when true. Default false.

static add(a, b) #

Creates a new Animated value composed from two Animated values added +Default is Easing.inOut(Easing.ease).

  • delay: Start the animation after delay (milliseconds). Default 0.
  • isInteraction: Whether or not this animation creates an "interaction handle" on the +InteractionManager. Default true.
  • useNativeDriver: Uses the native driver when true. Default false.

    • static spring(value, config) #

    Animates a value according to an analytical spring model based on +damped harmonic oscillation. +Tracks velocity state to create fluid motions as the toValue updates, and +can be chained together.

    Config is an object that may have the following options.

    Note that you can only define one of bounciness/speed, tension/friction, or +stiffness/damping/mass, but not more than one:

    The friction/tension or bounciness/speed options match the spring model in +Facebook Pop, Rebound, +and Origami.

    • friction: Controls "bounciness"/overshoot. Default 7.
    • tension: Controls speed. Default 40.
    • speed: Controls speed of the animation. Default 12.
    • bounciness: Controls bounciness. Default 8.

    Specifying stiffness/damping/mass as parameters makes Animated.spring use an +analytical spring model based on the motion equations of a damped harmonic +oscillator. +This behavior is slightly more precise and faithful to the physics behind +spring dynamics, and closely mimics the implementation in iOS's +CASpringAnimation primitive.

    • stiffness: The spring stiffness coefficient. Default 100.
    • damping: Defines how the spring’s motion should be damped due to the forces of friction. +Default 10.
    • mass: The mass of the object attached to the end of the spring. Default 1.

    Other configuration options are as follows:

    • velocity: The initial velocity of the object attached to the spring. Default 0 (object +is at rest).
    • overshootClamping: Boolean indiciating whether the spring should be clamped and not +bounce. Default false.
    • restDisplacementThreshold: The threshold of displacement from rest below which the +spring should be considered at rest. Default 0.001.
    • restSpeedThreshold: The speed at which the spring should be considered at rest in pixels +per second. Default 0.001.
    • delay: Start the animation after delay (milliseconds). Default 0.
    • isInteraction: Whether or not this animation creates an "interaction handle" on the +InteractionManager. Default true.
    • useNativeDriver: Uses the native driver when true. Default false.

    static add(a, b) #

    Creates a new Animated value composed from two Animated values added together.

    static divide(a, b) #

    Creates a new Animated value composed by dividing the first Animated value by the second Animated value.

    static multiply(a, b) #

    Creates a new Animated value composed from two Animated values multiplied together.

    static modulo(a, modulus) #

    Creates a new Animated value that is the (non-negative) modulo of the
