TypeScript React Native Flatlist: How to give renderItem the correct type of it's item?

I'm building a React Native app with TypeScript. renderItem complains that the destructured item implicitly has an any type. I googled and found this question and tried to implement what they teach here combined with the types in index.d.ts of the @types package for React Native.

export interface Props {  emotions: Emotion[];}class EmotionsPicker extends PureComponent<Props> {  keyExtractor = (item, index) => index;  renderItem = ({ item }) => (<ListItem title={item.name} checkmark={item.checked} />  );  render() {    return (<FlatList<Emotion>        keyExtractor={this.keyExtractor}        renderItem={this.renderItem}        data={this.props.emotions}      />    );  }}

Unfortunately this does not work. How can I give item the type Emotion?
