轮播返回空幻灯片

Question

当我在renderItem中使用return时，会显示一张空幻灯片

我的代码如下

<Carousel
  ref={c => {
    this._carousel = c;
  }}
  data={object}
  renderItem={({ item, index }) => this.render(item, index)}
  sliderWidth={sliderWidth}
  itemWidth={ITEM_WIDTH}
  contentContainerCustomStyle={{ alignItems: "center" }}
  activeSlideAlignment={"start"}
  inactiveSlideScale={1}
  inactiveSlideOpacity={1}
/>;

render(item, index) {
  if (index == 1) {
    return;
  } else {
    return (
      <View>
        <Text>1</Text>
      </View>
    );
  }
}

请帮助
