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.
class RefreshableList extends Component {
constructor(props) {
super(props);
this.state = {
refreshing: false,
};
}
_onRefresh = () => {
this.setState({refreshing: true});
fetchData().then(() => {
this.setState({refreshing: false});
});
}
render() {
return (
<FlatList
refreshControl={
<RefreshControl
refreshing={this.state.refreshing}
onRefresh={this._onRefresh}
/>
}
...
/>
);
}
...
}
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.
