Note: If you like the repo, please give it a star on github

Installation

npm install react-native-next-input --save

Usage

Import react-native-next input

import NextTextInput from 'react-native-next-input'

and then use it like this

<NextTextInput 
  noOfTextInput={4}
  textInputStyle={styles.textBox}
  onChangeValue={inputFromChildComponent}
  parentViewStyle={styles.textBoxes}
/>

where we are capturing the input from the child component in inputFromChildComponent like this

inputFromChildComponent = (combinedValueArray, currentValue, refForTheCurrentValue) => {
			console.log(combinedValueArray, currentValue,  refForTheCurrentValue)
	}

Clear Input

1. Pass a boolean state set to false initally to NextTextInput

<NextTextInput 
  noOfTextInput={4}
  textInputStyle={styles.textBox}
  onChangeValue={inputFromChildComponent}
  parentViewStyle={styles.textBoxes}
  clear={invalid}
  isInputCleared={isInputCleared}
/>

You can change clear the input by changing the state to true

verifyOTP = () => {
	try {
		if (currentNumbersEntered.length === 4) {
			phoneInstance.verifyOtp(currentNumbersEntered )
		
			props.navigation.navigate('SucessAuth') // Assume this throws error and code goes to catch statement
		} else {
			// To display error
			dropDownAlertRef.alertWithType('error', 'Error', frontendErrors.OTP_LENGTH)
		}
	} catch (err) {
		// Since user entered invalid otp, we decide to clear text in input box
		setInvalid(true) // this will clear input  
	}
}

inputFromChildComponent = (combinedValueArray, currentValue, refForTheCurrentValue) => {
	if (clear) {
		// If you have cleared the state or passed true in clear props, it's recommended that you re-change it to false
		setClear(false)
	}
	console.log(combinedValueArray, currentValue,  refForTheCurrentValue)
}
