I have a horizontal FlatList in my React Native iOS app. At the bottom of the screen, the FlatList is displayed with 5 items. If you click on the last item (scrolled all the way to the right), the screen will refresh and the FlatList will remain scrolled to the right. How can I get the FlatList to always reset the scroll position (to scroll from the beginning) when the screen changes?
Edit: I have a feeling that my screen is not actually "refreshing" but rather merely changing the data shown on the screen. In this case I may need to trigger a refresh of the screen somehow to cause the FlatList to reset the scroll position? Any help would be greatly appreciated!
const HorizontalScroll = ({items, handlePress}) => {
const renderItem = ({item}) => {
const itemData = { color: item.color, title: item.title };
return <HorizontalItem itemData={itemData} handlePress={handlePress} />;
};
return (
<View style={styles.container}>
<FlatList
data={items}
renderItem={renderItem}
horizontal={true}
numColumns={1}
key={(item) => item.id}
initialNumToRender={5}
scrollToIndex={0}
ItemSeparatorComponent={() => <View style={{width: 8}} />}>
</FlatList>
</View>
);
};
I solved this problem by forcing a refresh of the component. Specifically, I added a key prop to my component so that every time the key value changes, it remounts the component. This causes the FlatList to reset the scroll position to the beginning.
<View key={items[0].title}>
{content}
</View>
