This component is used inside a ScrollView or ListView to add pull to refresh functionality. When the ScrollView is at scrollY: 0, swiping down triggers an onRefresh event.

Example

import React from 'react';

import {

ScrollView,

RefreshControl,

StyleSheet,

Text,

SafeAreaView,

} from 'react-native';

import Constants from 'expo-constants';

const wait = (timeout) => {

return new Promise(resolve => {

setTimeout(resolve, timeout);

});

}

const App = () => {

const [refreshing, setRefreshing] = React.useState(false);

const onRefresh = React.useCallback(() => {

setRefreshing(true);

wait(2000).then(() => setRefreshing(false));

}, []);

return (

<SafeAreaView style={styles.container}>

<ScrollView

contentContainerStyle={styles.scrollView}

refreshControl={

<RefreshControl refreshing={refreshing} onRefresh={onRefresh} />

}

>

<Text>Pull down to see RefreshControl indicator</Text>

</ScrollView>

</SafeAreaView>

);

}

const styles = StyleSheet.create({

container: {

flex: 1,

marginTop: Constants.statusBarHeight,

},

scrollView: {

flex: 1,

backgroundColor: 'pink',

alignItems: 'center',

justifyContent: 'center',

},

});

export default App;

Note: refreshing is a controlled prop, this is why it needs to be set to true in the onRefresh function otherwise the refresh indicator will stop immediately.
