How to check when the focus is lost in a React Native TextInput?
To check when the focus is lost in a React Native TextInput, we can set the onBlur prop to a function that runs when focus is lost.
For instance, we write:
import * as React from 'react';
import { TextInput, View } from 'react-native';
import Constants from 'expo-constants';
import { Card } from 'react-native-paper';
import { Icon } from 'react-native-elements';
export default function App() {
return (
<View>
<TextInput onBlur={() => console.log('focus lost')} placeholder="Name" />
</View>
);
}
to set the onBlur prop to a function that logs 'focus lost' when we move focus away from the text input.
Conclusion
