After switching to any image other than the first one in the carousel, when the browser size changes, the Pagination position is correct and the carousel displays the first image

To address the issue of the carousel resetting to the first image when the browser size changes, you can use the useCommonVariables hook from the react-native-reanimated-carousel library. This hook helps adjust the handlerOffset when the size of the carousel changes, ensuring that the carousel maintains the correct position.

Here's a relevant code snippet using useAnimatedReaction to listen for size changes:

useAnimatedReaction(
  () => {
    const previousSize = prevSize.value;
    const isSizeChanged = previousSize !== size;
    const shouldComputed = isSizeChanged;

    if (shouldComputed) prevSize.value = size;

    return {
      shouldComputed,
      previousSize,
      size,
    };
  },
  ({ shouldComputed, previousSize, size }) => {
    if (shouldComputed) {
      handlerOffset.value = computeOffsetIfSizeChanged({
        handlerOffset: handlerOffset.value,
        prevSize: previousSize,
        size,
      });
    }
  },
  [size]
);

This approach helps maintain the carousel's position accurately across different screen sizes [1][2].

要解决在浏览器大小更改时轮播重置为第一张图像的问题,您可以使用库中的钩子。此挂钩有助于调整轮播大小的变化,确保轮播保持正确的位置。useCommonVariables``react-native-reanimated-carousel``handlerOffset

下面是用于侦听大小更改的相关代码片段:useAnimatedReaction

useAnimatedReaction(
() => {
const previousSize = prevSize.value;
const isSizeChanged = previousSize !== size;
const shouldComputed = isSizeChanged;

if (shouldComputed) prevSize.value = size;

return {
  shouldComputed,
  previousSize,
  size,
};

},
({ shouldComputed, previousSize, size }) => {
if (shouldComputed) {
handlerOffset.value = computeOffsetIfSizeChanged({
handlerOffset: handlerOffset.value,
prevSize: previousSize,
size,
});
}
},
[size]
);
此方法有助于在不同屏幕尺寸上准确保持轮播的位置[1][2].
