Answer 1

Here I have created a screen with Six text input for otp verfication with Resend OTP functionality with counter timer of 90 sec. Fully tested on both android and ios.

I have used react-native-confirmation-code-field for underlined text input. Below is the complete code.

import React, { useState, useEffect } from 'react';
import { SafeAreaView, Text, View ,TouchableOpacity} from 'react-native';
import { CodeField, Cursor, useBlurOnFulfill, useClearByFocusCell } from 
'react-native-confirmation-code-field';
import { Button } from '../../../components';
import { styles } from './style';

interface VerifyCodeProps {
}
const CELL_COUNT = 6;
const RESEND_OTP_TIME_LIMIT = 90;

export const VerifyCode: React.FC = () => {
let resendOtpTimerInterval: any;

const [resendButtonDisabledTime, setResendButtonDisabledTime] = useState(
    RESEND_OTP_TIME_LIMIT,
);

//to start resent otp option
const startResendOtpTimer = () => {
    if (resendOtpTimerInterval) {
        clearInterval(resendOtpTimerInterval);
    }
    resendOtpTimerInterval = setInterval(() => {
        if (resendButtonDisabledTime <= 0) {
            clearInterval(resendOtpTimerInterval);
        } else {
            setResendButtonDisabledTime(resendButtonDisabledTime - 1);
        }
    }, 1000);
};

//on click of resend button
const onResendOtpButtonPress = () => {
    //clear input field
    setValue('')
    setResendButtonDisabledTime(RESEND_OTP_TIME_LIMIT);
    startResendOtpTimer();

    // resend OTP Api call
    // todo
    console.log('todo: Resend OTP');
};

//declarations for input field
const [value, setValue] = useState('');
const ref = useBlurOnFulfill({ value, cellCount: CELL_COUNT });
const [props, getCellOnLayoutHandler] = useClearByFocusCell({
    value,
    setValue,
});

//start timer on screen on launch
useEffect(() => {
    startResendOtpTimer();
    return () => {
        if (resendOtpTimerInterval) {
            clearInterval(resendOtpTimerInterval);
        }
    };
}, [resendButtonDisabledTime]);

return (
    
        Verify the Authorisation Code
        Sent to 7687653902
         (
                
                    
                        {symbol || (isFocused ?  : null)}
                    
                
            )}
        />
        {/* View for resend otp  */}
        {resendButtonDisabledTime > 0 ? (
            Resend Authorisation Code in {resendButtonDisabledTime} sec
        ) : (
                
                    
                         Resend Authorisation Code
                         in {resendButtonDisabledTime} sec
                    
                
            )
        }
        
            
                    console.log("otp is ", value)
                } />
        
    
);
}

Style file for this screen is in given below code:

import { StyleSheet } from 'react-native';
import { Color } from '../../../constants';

export const styles = StyleSheet.create({
root: {
    flex: 1,
    padding: 20,
    alignContent: 'center',
    justifyContent: 'center'
},
title: {
    textAlign: 'left',
    fontSize: 20,
    marginStart: 20,
    fontWeight:'bold'
},
subTitle: {
    textAlign: 'left',
    fontSize: 16,
    marginStart: 20,
    marginTop: 10
},
codeFieldRoot: {
    marginTop: 40,
    width: '90%',
    marginLeft: 20,
    marginRight: 20,
},
cellRoot: {
    width: 40,
    height: 40,
    justifyContent: 'center',
    alignItems: 'center',
    borderBottomColor: '#ccc',
    borderBottomWidth: 1,
 },
 cellText: {
    color: '#000',
    fontSize: 28,
    textAlign: 'center',
},
focusCell: {
    borderBottomColor: '#007AFF',
    borderBottomWidth: 2,
},

button: {
    marginTop: 20
},
resendCode: {
    color: Color.BLUE,
    marginStart: 20,
    marginTop: 40,
},
resendCodeText: {
    marginStart: 20,
    marginTop: 40,
},
resendCodeContainer: {
    flexDirection: 'row',
    alignItems: 'center'
}
})

Hope it will be helpful for many. Happy Coding!!
