意外令牌，预期，错误(反应导航)

Question

如果收到outfitDetail道具，我会在标题标题处渲染用户的图像和用户名。

class OutfitDetail extends Component {
  static navigationOptions = ({navigation, screenProps}) => ({
    ...
    headerTitle: (
      !!screenProps.outfitDetail ? (
            <View style={styles.container}>
              <TouchableOpacity onPress={() => this.props.navigation.navigate('Profile', {id: userId})}>
                {this._renderAvatar(screenProps.outfitDetail.user.image)}
              </TouchableOpacity>
              <View style={styles.content}>
                <View style={styles.contentHeader}>
                  <RkText rkType='header5'>{screenProps.outfitDetail.user.username}</RkText>
                  <RkText rkType='secondary4 hintColor'>
                    <TimeAgo time={screenProps.outfitDetail.publish}/>
                  </RkText>
                </View>
                <RkText rkType='primary3 mediumLine'>{screenProps.outfitDetail.content}</RkText>
              </View>
            </View>
      ): (<Text>Loading</Text>)
    ),
    ...
  });

因此，如果 screenProps.outfitDetail 不为空（尚未获取），它将呈现加载，否则将呈现用户的照片和用户名。

为什么我会Unexpected token, expected , error (React-navigation)？错误发生在上面的第三行代码上。

  ):(<Text>Loading</Text>)
),
... other functions ...
})
