Center items with aspect ratio in FlatList - React Native - css

Question

This seems like an easy question at first but it's actually tricky.
Better to go directly to the example. I've created a snack with the sample code here https://snack.expo.io/BkSNtNrWV
I want to have a list of items with given aspect ratio (say 3:2) and the items should take as much space as possible with a maximum limit on size. This sample code does it:
<View>
<FlatList style={{backgroundColor:'lightgray'}}
data={[{key: 'a'},{key: 'b'}]}
renderItem={({item}) =>
<View style ={styles.pink}></View>
}/>
</View>
const styles = StyleSheet.create({
pink: {
backgroundColor: "#A37E93",
maxHeight: 150,
aspectRatio: 3/2,
borderWidth: 1,
}});
And this is the result:
However, the problem is that I would like to have the items aligned to the center. I tried to wrap the list item in a flexbox with 'row' direction but that caused the item to have 0 height => not displayed. Justify content didn't help either (it's possible that I do it incorrectly).
Does anyone know how to solve this please?

Updated the code. Add flex to inner item and wrap the view inside another with screen width.
import * as React from 'react';
import { Text, View, StyleSheet,FlatList,Dimensions } from 'react-native';
import { Constants } from 'expo';
const{width} = Dimensions.get('window')
// You can import from local files
import AssetExample from './components/AssetExample';
// or any pure javascript modules available in npm
import { Card } from 'react-native-paper';
export default class App extends React.Component {
render() {
return (
<View>
<FlatList style={{backgroundColor:'lightgray'}}
data={[{key: 'a'},{key: 'b'}]}
renderItem={({item}) =>
<View style={styles.item}>
<View style ={styles.pink}></View>
</View>
}
/>
</View>
);
}
}
const styles = StyleSheet.create({
item:{
width:width,
height:150,
alignItems:'center'
},
pink: {
flex:1,
backgroundColor: "#A37E93",
maxHeight:150,
aspectRatio:3/2,
borderWidth:1,
}
});
