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

Currently _signInPhoneNumber is deprecated, so use this:

try {
    AuthCredentialauthCredential = PhoneAuthProvider.getCredential(verificationId: verificationId, verificationsCode: smsCode);

    await _firebaseAuth
      .signInWithCredential(authCredential)
      .then((FirebaseUser user) async {
         final FirebaseUser currentUser = await _firebaseAuth.currentUser();
         assert(user.uid == currentUser.uid);
         print('signed in with phone number successful: user -> $user');
    }
}
