Passing current /
Ask your Question
So I'm probably missing something fundamental; but is there an example of passing the currently active page to a child?
I'm doing something very similar to the Basic example, but I would like to pass the current active page to a child. Unfortunately setting a state variable using the selectPageCallback re-renders the parent, and the animated view goes back to the initialPage={0} basically just flickers back.
This happens as soon as you set any kind of state variable.
Would love any pointers or ideas! (quite a react novice so I'm probably just doing something very bad :) )
Some of my sample code:
const setPage = useCallback(
(page) =>
pagerRef.current?.setPage(page),
[]
);
const data = [
{
key: 0,
title: 'A good child,
view: <ChildView nextPage={setPage}></ChildView >,
...
},
<AnimatedPagerView
style={{ flex: 1 }}
initialPage={0}
ref={pagerRef}
scrollEnabled={true}
draggable={true}
onPageScroll={onPageScroll}
onPageSelected={onPageSelected}
>
{useMemo(() => {
return data.map(({ key, title, view }) => (
<View key={key}>
{view}
</View>
));
}, [data])}
</AnimatedPagerView>
```
Now in my world I would do something like this:
const onPageSelected = useCallback(({ nativeEvent }) => { setActivePage(nativeEvent.position); }, []);
<ChildView nextPage={setPage} activePage={activePage}></ChildView >
You could set your initialPage to the activePage initialPage={activePage}
I think that would solve the flicker.
