React Native FlatList with columns, Last item width
You can try to get the current width of the device via Dimensions, do some math based on the number of columns you want to render, minus off the margins and set that as the minWidth and maxWidth.
For example:
const {height, width} = Dimensions.get('window');
const itemWidth = (width - 15) / 2;
<View style={{ flex: 1, margin: 5, backgroundColor: '#ddd', minWidth: {this.itemWidth}, maxWidth: {this.itemWidth}, height: 130}} ></View>
Theres a few things you can try here.
A) Setting a pre-defined width for the card ( Maybe equal to the height you've set? ). Then you can use alignItems
in order to have the card positioned in the middle or on the left - Unsure as to which you wanted here.
B) If there are an even number of cards, you could add an empty View at the end in order to fill this space. I find this method pretty clunky but useful when trying to leave space for future elements.
C) Simply use alignItems: 'space-between
, i like to use this to center items, but you would have to define the width, or use something like flex:0.5
I suggest researching more into flexbox to help you with this, as it is hard to tell the context of this situation. I'm assuming the above methods will help, but if not, here are some links for you to look at -

Hope this helps. If you need any further clarification - just ask
for your case use flex: 1/2
therefore: Your item should have flex of 1/(number of columns) if you have 3 columns your item should have flex:1/3
This is the cleanest way to style a FlatList
with columns and spaced evenly:
<FlatList style={{margin:5}}
numColumns={2} // set number of columns
columnWrapperStyle={style.row} // space them out evenly
data={this.state.items}
keyExtractor={(item, index) => item.id }
renderItem={(item) => <Card image={item.item.gallery_image_url} text={item.item.name}/> }
/>
const style = StyleSheet.create({
row: {
flex: 1,
justifyContent: "space-around"
}
});
