In my App.js file, I have the following code snippets:
- The
reffor the main FlatList is set in auseEffecthook asflatListRef
const [flatListRef, setFlatListRef] = useState(null);
...
useEffect(() => {
let mounted = true;
if (refSlides?.current && mounted) setFlatListRef(refSlides.current);
return () => mounted = false;
}, []);
- The function
renderItemis responsible for rendering the desired component as an item of the FlatList
const renderItem = ({item, index, separators}) => {
// Code here to render components based on conditions
};
- The actual definition of the FlatList
<FlatList
data={slides}
ref={refSlides}
keyExtractor={item => item.key.toString()}
renderItem={renderItem}
getItemLayout={(data, index) => {
// Layout calculations here
}}
horizontal={true}
showsHorizontalScrollIndicator={false}
pagingEnabled={true}
/>
In components like Welcome, Hospital, Snippets, or Disease, I have this piece of code:
// Code snippet here
I am facing issues when trying to auto-scroll to the last added item. The error message indicates that the requested index is out of range.
Despite having multiple items in the FlatList, the error states: "maximum is 1". This behavior has been puzzling me for days.
If you have any insights or suggestions, please share them. Thank you!
