Let’s break down the key aspects of the code:<\/p>\n
Component Properties:<\/strong> The component takes a single property openCard, which is a boolean that indicates whether the card should be open or not.<\/p>\nAnimated Value:<\/strong> The useRef hook is employed to create a persistent reference named animationRef to the Animated.Value. This helps maintain the value between re-renders and avoids unnecessary reinitialization.<\/p>\nAnimation Logic:<\/strong> The useEffect hook is utilized to manage the animation behavior based on changes in the openCard prop. It calculates the target value for the animation and selects an appropriate easing function (smooth acceleration and deceleration). Then, it configures the animation parameters using the Animated.timing method.<\/p>\nJSX Rendering:<\/strong> The component returns JSX representing an Animated.View. The transform style property is used to apply the animation to the horizontal translation (translateX) of the card. The value is set to the animationRef, which reflects the animated value.<\/p>\nBy combining these elements, the CardCashout component effectively animates the card’s transition from left to right and vice versa when the openCard prop changes.<\/p>\n","protected":false},"excerpt":{"rendered":"
