Answer by skyplor for 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>
