![]() ![]() Specifying stiffness/damping/mass as parameters makes Animated.spring use an analytical spring model based on the motion equations of a damped harmonic oscillator. speed: Controls speed of the animation.friction: Controls "bounciness"/overshoot.The friction/tension or bounciness/speed options match the spring model in Facebook Pop, Rebound, and Origami. Note that you can only define one of bounciness/speed, tension/friction, or stiffness/damping/mass, but not more than one: ![]() Tracks velocity state to create fluid motions as the toValue updates, and can be chained together.Ĭonfig is an object that may have the following options. Default 0.Īnimates a value according to an analytical spring model based on damped harmonic oscillation. delay: Start the animation after delay (milliseconds).easing: Easing function to define curve.duration: Length of animation (milliseconds).The Easing module has tons of predefined curves, or you can use your own function. Default false.Īnimates a value along a timed easing curve. useNativeDriver: Uses the native driver when true.isInteraction: Whether or not this animation creates an "interaction handle" on the InteractionManager.decay() static decay (value, config )Īnimates a value from an initial velocity to zero based on a decay coefficient.Ĭonfig is an object that may have the following options: fadeAnim, // The value to drive instead of a scalar. timing ( // Animate value over time this. The simplest workflow for creating an animation is to create an Animated.Value, hook it up to one or more style attributes of an animated component, and then drive updates via animations using Animated.timing(): Animated. Animated focuses on declarative relationships between inputs and outputs, with configurable transforms in between, and simple start/ stop methods to control time-based animation execution. The Animated library is designed to make animations fluid, powerful, and easy to build and maintain. ![]()
