[Alamut98]

while adding react-native-pagination in react-native-swipe-list-view it shows the below eror.

my code is
render() {
return (

{this.state.listType === 'FlatList' &&
<React.Fragment>
<SwipeListView
useFlatList
data={this.state.listViewData}
renderItem={ (data, rowMap) => (

I am {data.item.text} in a SwipeListView

)}
leftOpenValue={75}
rightOpenValue={-150}
previewRowKey={'0'}
previewOpenValue={-40}
previewOpenDelay={3000}
onRowDidOpen={this.onRowDidOpen}
onSwipeValueChange={this.onSwipeValueChange}
ref={r=>this.refs=r}
keyExtractor={(item, index) => index.toString()}
onViewableItemsChanged={this.onViewableItemsChanged}
viewabilityConfig={this.viewabilityConfig}
/>
