OneTapInput and ResendOTPButton Components

The OneTapInput and ResendOTPButton are custom, reusable components for React-Native applications. They are designed to handle OTP (One Time Password) input and resend OTP functionality respectively. This component utilizes the react-native-otp-verify component for OTP Autofill functionality.

Prerequisites

Before you can use the OneTapInput and ResendOTPButton components, you need to install the react-native-otp-verify package. You can do this by running the following command in your terminal:

npm install react-native-otp-verify

or if you are using yarn:

yarn add react-native-otp-verify

Usage

Permissions: Android

Before using the OneTapInput and ResendOTPButton components on android, you need to add the following permissions in your AndroidManifest.xml file for otp verify to work:

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />

Hash Code During Development

For otp auto verify to work, you need to format the incoming sms in this way: <#> Your Otp is: 123ABC78. Use this code to log in. YOURHASHCODE <#> You have to replace YOURHASHCODE with the hash code you are getting from getHashCode function.

Hash Code During Production

To generate the hash code for production, you need to follow these steps:

Obtain the SHA-256 certificate fingerprints for your app. You can do this by running the following command in your terminal:
```
keytool -list -v -keystore my-release-key.keystore
```
Replace my-release-key.keystore with the path and name of your actual keystore file.
Once you have the SHA-256 certificate fingerprint, you can use it to generate your app's hash string. The hash string is created by concatenating your app's package name with the SHA-256 certificate, and then applying a specific algorithm to it. You can use an online tool like this one provided by Google to generate the hash string. You can use an online tool like this one provided by Google to generate the hash string.
After generating the hash string, replace YOURHASHCODE in the SMS format with this hash string. Please note that the hash code for debug and release versions will be different due to the different signing keys used.

// If you are using js/jsx instead of ts/tsx, remove the types. (i.e.: <string>, :string, type declaration/s).
import { useState } from "react";
import { OneTapInput, ResendOTPButton } from "react-native-onetapinput";

const App = () => {
  const [hash, setHash] = useState<string[]>([]);
  const [otp, setOtp] = useState<string>("");

  return (
    <>
      <OneTapInput
        getFinalOtp={(otp: string) => {
          console.log("Final OTP: ", otp);
          setOtp(otp);
        }}
        getHashCode={(hash: string[]) => {
          console.log("Hash code ===> ", hash);
          setHash(hash); // The hash to be used in the SMS receiver app format: <#> Your Otp is: 123ABC78. Use this code to log in. YOURHASHCODE <#> (You have to place the hashcode at the end of your sms)
        }}
      />
      <ResendOTPButton
        onResendOtp={() => {
          // Handle Resend OTP Logic
        }}
      />
    </>
  );
};

export default App;
