How to select the next TextInput after pressing the "next" keyboard button in react native?

Steps:

1. Use ref to Control Focus
   
   Assign a ref to each TextInput to programmatically control focus.

2. Handle onSubmitEditing
   
   Use the onSubmitEditing event to focus the next input.

3. Set returnKeyType
   
   Set returnKeyType to "next" for intermediate fields and "done" for the last one.

4. Prevent Keyboard Dismissal
   
   Use blurOnSubmit={false} to keep the keyboard open while navigating.

Code Example:

import React, { useRef } from 'react';
import { TextInput, View, StyleSheet } from 'react-native';

const App = () => {
  const input1Ref = useRef(null);
  const input2Ref = useRef(null);
  const input3Ref = useRef(null);

  return (
    <View style={styles.container}>
      <TextInput
        ref={input1Ref}
        style={styles.input}
        placeholder="Input 1"
        returnKeyType="next"
        onSubmitEditing={() => input2Ref.current?.focus()}
        blurOnSubmit={false}
      />
      <TextInput
        ref={input2Ref}
        style={styles.input}
        placeholder="Input 2"
        returnKeyType="next"
        onSubmitEditing={() => input3Ref.current?.focus()}
        blurOnSubmit={false}
      />
      <TextInput
        ref={input3Ref}
        style={styles.input}
        placeholder="Input 3"
        returnKeyType="done"
        onSubmitEditing={() => console.log('Form submitted')}
      />
    </View>
  );
};

const styles = StyleSheet.create({
  container: { flex: 1, justifyContent: 'center', padding: 16 },
  input: { height: 50, borderColor: 'gray', borderWidth: 1, marginBottom: 10, paddingHorizontal: 10 },
});

export default App;
