Horizontal Flatlist: Space between items - css

Question

I'm trying to get space around my items in a horizontal flatlist, no matter how I try it doesn't seem to work:
const renderItem = ({item}) => {
return (
<View style={styles.item}>
<Image
source={{uri: content.uri}}
style={styles.image}
/>
<View>
<Text style={styles.contentTitle}>{content.title}</Text>
<Text style={styles.contentText}>{content.releaseDate}</Text>
</View>
</View>
)
}
<View style={styles.container}>
{header}
<View style={{width: '100%', justifyContent: 'space-around', backgroundColor: 'green'}}>
<FlatList
data={data}
pagingEnabled={true}
horizontal={true}
renderItem={renderItem}
keyExtractor={item => item.id}
ref={flatList}
/>
</View>
</View>
const styles = StyleSheet.create({
container: {
width: windowWidth,
marginTop: 15,
paddingBottom: 15,
borderBottomWidth: 1,
borderBottomColor: Colors.borderBlue,
backgroundColor: Colors.backgroundGenericTransparent,
},
item: {
width: windowWidth / 3.1,
backgroundColor: 'red',
},
image: {
width: '100%',
height: 220,
},
})
result:
As you can see the items are all together on the left even though I have added a space-around property on the container. Not show how I can resolve this.

Answer 1

use ItemSeparatorComponent
<FlatList
data={data}
pagingEnabled={true}
horizontal={true}
renderItem={renderItem}
keyExtractor={item => item.id}
ref={flatList}
ItemSeparatorComponent={() => {
return (
<View
style={{
height: "100%",
width: 10,
}} />
);
}}
/>

Answer 2

Use this prop on flatlist:
columnWrapperStyle={{ justifyContent: "space-between" }}

Answer 3

Not sure what you are trying to achieve.
Is that what you want?

Just add horizontal padding to your container. and no matter how big your items get you will always have spacing left and right. If the item gets too big you can start to scroll.

Answer 4

<View style={styles.messageGalleryContainer}>
<FlatList
data={files}
renderItem={renderImageGalleryItem}
keyExtractor={(item) => item?._id}
horizontal
showsHorizontalScrollIndicator={false}
ItemSeparatorComponent={() => <View style={{ width: 10 }} />} // add this line
contentContainerStyle={styles.messageGalleryItemContainer}
/>
</View>
You should use ItemSeparatorComponent with an empty component or with any element you want.
