How to do Phone Authentication in Flutter using Firebase?

Question

I have searched many websites and I didn\'t find a way to implement phone authentication in Flutter using Firebase. Can anyone tell me how to this?

Answer 1

Use the flutter_otp package to send SMS with OTP easily. The advantages are:

1. You can send custom OTP messages.
2. OTP can be generated in any range.

Example of using it :

 import 'package:flutter_otp/flutter_otp.dart';

 ...

 FlutterOtp myOtpObj = FlutterOtp();
 myOtpObj.sendOtp('7975235555');

 ...

 // you can check as follows
 bool correctOrNot = myOtpObj.resultChecker();
