Introduction

Phone Email presents a revolutionary solution for user authentication - "Sign in with Phone". Our plugin enables mobile apps & websites to offer seamless phone number verification to users, enhancing security and user experience. Similar to Firebase phone authentication, our solution embeds a "Log in with phone" button on client websites. Upon clicking, a verification window prompts users to enter their country code and mobile number. After successful verification through OTP sent to the user's mobile, control redirects back to the client website with an access token. Subsequently, passing this access token to the getuser REST API retrieves the verified mobile number.

Key Benefits:

• Cost-Effective: Minimal or no cost for phone verification.
• Enhanced Security: OTP-based verification ensures secure authentication.
• Seamless Integration: Easy integration into existing web applications.
• Improved User Experience: Streamlined authentication process for users.

Installation

To integrate the "Sign in with Phone" functionality into your Next.js project, follow these steps:

1. Clone the repository:

   git clone https://github.com/phoneemail/sign-in-with-phone-flutter-app.git

2. Navigate to the project directory:

   cd sign-in-with-phone-flutter-app

3. Install dependencies:

   dependencies:
   phone_email_auth: ^0.0.3
   
   //Run following command to sync dependencies
   flutter pub get

4. Initialization:

   PhoneEmail.initializeApp(clientId: 'YOUR_CLIENT_ID',);

   Note:

   clientId : Set clientId which you obtained from Profile Details section of Admin Dashboard of Phone Email.

5. Add Phone Email Login Button

    child: PhoneLoginButton(
    borderRadius: 8,
    buttonColor: Colors.teal,
    label: 'Sign in with Phone',
    onSuccess: (String accessToken, String jwtToken) {
        if (accessToken.isNotEmpty) {
        setState(() {
            userAccessToken = accessToken;
            jwtUserToken = jwtToken;
            hasUserLogin = true;
        });
        }
    },
    )

   The PhoneLoginButton will return the accessToken and jwtToken, which are necessary for obtaining the verified phone number.

6. Get Verified phone number:

   Once you've obtained the accessToken, get verified phone number by calling the getUserInfo() function. Use the following code snippet to retrieve the verified phone number.

    PhoneEmail.getUserInfo(
    accessToken: userAccessToken,
    clientId: phoneEmail.clientId,
    onSuccess: (userData) {
        setState(() {
        phoneEmailUserModel = userData;
        var countryCode = phoneEmailUserModel?.countryCode;
        var phoneNumber = phoneEmailUserModel?.phoneNumber;
   
        // Use this verified phone number to register user and create your session
   
        });
    },
    );

7. Display Email Alert:

   Integrate an email alert icon on your screen for a successfully authenticated user. Use the following code snippet to fetch the unread email count and display the email icon.

   floatingActionButton: hasUserLogin
       ? EmailAlertButton(
       jwtToken: jwtUserToken,
       ) : const Offstage(),
   );
