如何将标题放置在react-native-elements 1.0.0-beta5列表项的最右端

Question

我正在为ListItem使用带有徽章和V形符号的正确标题。但是，正确的标题并不位于最右上方。这是我的代码。

<ListItem
  onPress={() => {
    this.props.navigation.navigate ('Messages', {
      message: item,
    });
  }}
  scaleProps={{
    friction: 90,
    tension: 100,
    activeScale: 0.95,
  }}
  linearGradientProps={{
    colors: ['#eee', '#81c784'],
    start: {x: 1, y: 0},
    end: {x: 0.2, y: 0},
  }}
  ViewComponent={LinearGradient}
  leftAvatar={{
    rounded: true,
    source: {uri: item.avatar_url},
  }}
  rightTitle="date"
  rightTitleStyle={{position: 'fixed', right: 0}}
  title={item.name}
  titleStyle={{color: '#000', fontWeight: 'bold'}}
  subtitleStyle={{color: '#000'}}
  subtitle={item.subtitle}
  chevronColor="gray"
  badge={{
    value: 3,
    textStyle: {color: '#fff'},
    containerStyle: {backgroundColor: '#81c784'},
  }}
  chevron
/>

如何在最右上角显示列表项的日期？
