Question

滑动式-card.js：

render() {
  const {
    children, containerStyle, revealContainerStyle, rightSwipeContent,
  } = this.props;

const swipeAnimStyle = {
  right: this.swipeAnim,
};

const childrenWithProps = React.Children.map(children, child => React.cloneElement(child, {
  swipeLeftPanResponder: this.swipeLeftPanResponder,
}));

return (
  <View style={[styles.container, containerStyle]}>
    <Animated.View style={[styles.swipedSection, swipeAnimStyle]}>
      {childrenWithProps}
    </Animated.View>

    <View
      style={[styles.revealedContainer, revealContainerStyle]}
    >
      {rightSwipeContent()}
    </View>
  </View>
);
}

正在使用上述组件，如下所示：

renderStory({ item }: Object) {
  const story = this.props.feeds.byId[item];

return (
  <SwipeableCard
    key={item}
    containerStyle={styles.feedCard}
    rightSwipeContent={this.renderSwipeContent(story, this.props.portfolios)}
  >
    <StoryCard story={story} onStoryPress={this.onStoryPress(item)} />
  </SwipeableCard>
);
}

我收到以下代码提供的流错误消息：

无法调用React.Children.map，因为缺少属性map Children

Answer 1

它适用于我，它是in the type definition for React。这是一个Try Link。我敢打赌，本地和全球版本的流程之间存在差异，而且您运行的是过时的版本：

yarn upgrade flow@0.70
./node_modules/.bin/flow

这应该可以运行本地版本（或在package.json中定义任务）。

Flowjs：React.Children.map中缺少map属性
