Sometimes, we want to scroll to end of FlatList after displaying the keyboard with React Native.

In this article, we’ll look at how to scroll to end of FlatList after displaying the keyboard with React Native.

How to scroll to end of FlatList after displaying the keyboard with React Native?

To scroll to end of FlatList after displaying the keyboard with React Native, we can set the onLayour prop to a function that calls scrollToEnd on the FlatList’s ref.

For instance, we write:

import * as React from 'react';
import { FlatList, Text, View } from 'react-native';
import Constants from 'expo-constants';
import { Card } from 'react-native-paper';

const flatListItems = Array(200)
  .fill()
  .map((_, i) => ({ title: i, id: i }));

const Item = ({ title }) => (
  <View
    style={{
      backgroundColor: '#f9c2ff',
      padding: 20,
      marginVertical: 8,
      marginHorizontal: 16,
    }}>
    <Text>{title}</Text>
  </View>
);

export default function App() {
  const renderItem = ({ item }) => <Item title={item.title} />;
  const flatListRef = React.useRef();

  return (
    <View style={{ height: 300 }}>
      <FlatList
        ref={flatListRef}
        data={flatListItems}
        renderItem={renderItem}
        keyExtractor={(item) => item.id}
        onLayout={() => flatListRef.current.scrollToEnd({ animated: true })}
      />
    </View>
  );
}

to set onLayout to a function that calls flatListRef.current.scrollToEnd to scroll the FlatList to the end.

We create the ref with useRef and assigned it as the value of the FlatList‘s ref prop.

Conclusion

To scroll to end of FlatList after displaying the keyboard with React Native, we can set the onLayour prop to a function that calls scrollToEnd on the FlatList’s ref.
