I'm building a React Native app using TypeScript. I'm trying to use a SectionList
. I followed the docs, and here is my code:
renderSectionHeader = ({ section: { title } }: { section: { title: string } }) => (
<ListItem title={title} />
);
render() {
const { sections } = this.props;
return (
<SafeAreaView style={styles.container}>
<SectionList
keyExtractor={this.keyExtractor}
sections={[
{title: 'Title1', data: ['item1', 'item2']},
{title: 'Title2', data: ['item3', 'item4']},
{title: 'Title3', data: ['item5', 'item6']},
]}
renderItem={this.renderItem}
renderSectionHeader={this.renderSectionHeader}
/>
</SafeAreaView>
);
}
But the line renderSectionHeader={this.renderSectionHeader}
throws the following TSLint Error:
[ts]
Type '({ section: { title } }: { section: { title: string; }; }) => Element' is not assignable to type '(info: { section: SectionListData<any>; }) => ReactElement<any> | null'.
Types of parameters '__0' and 'info' are incompatible.
Type '{ section: SectionListData<any>; }' is not assignable to type '{ section: { title: string; }; }'.
Types of property 'section' are incompatible.
Type 'SectionListData<any>' is not assignable to type '{ title: string; }'.
Property 'title' is missing in type 'SectionListData<any>'. [2322]
Are the types of SectionList
broken? Or is the example wrong? Or am I doing something wrong?
