Rei*_*oot 11 ref reactjs react-native recompose
我正在尝试在React Native中添加一个函数组件的ref,以便在FlatList组件上使用scrollToEnd.
我想使用重构为此,并且正如他们的文档所述,toClass()应该能够处理这个问题.但是,没有给出任何例子.
目前,这是我失败的实施.有人能告诉我我做错了什么吗?
我非常感激!

import { commentsQuery } from '../../queries/comments';
const CommentScreen = ({ onRef, currentUser, data: { comments, loading } }) => {

return (
<View>
<Text>Loading...</Text>

}
return (
<FlatList
ref={ref => {
this.refs.commentList = ref;
}}
data={comments}
keyExtractor={item => item.id}
renderItem={({ item }) => <CommentItem {...item} currentUser={currentUser} />}
/>
);
};
export default compose(
toClass,
graphql(commentsQuery),
lifecycle({
componentDidMount() {
console.log('PROPZZZ', this.commentList);
},
}),
)(CommentScreen);
CommentScreen.propTypes = {
fetchComments: PropTypes.func.isRequired,
updateId: PropTypes.number.isRequired,
comments: PropTypes.arrayOf(Object),
text: PropTypes.string.isRequired,
};
