VisualizaçõesHow to make ScrollView automatically go back to origin?
I have a ScrollView like this:
const CustomComp=React.memo(({props...})=>{
return(<ScrollView horizontal={true}>
{content...}
</ScrollView>);
});
and when I scroll to the right and then re render, the x position of the Scroll stays the same
how do I get it to go back to x=0 every time it re renders?

You can use useEffect hook and ScrollView's scrollTo method.
Here is a snack to test it: https://snack.expo.dev/@truetiem/scroll-to-top-when-re-rendered
First create a ref for scroll view.
const scrollRef = useRef();
<ScrollView ref={scrollRef} horizontal>
And scroll to top when useEffect triggered.
useEffect(() => {
scrollRef.current?.scrollTo({ x: 0, y: 0, animated: true });
});
