        await FirebaseAuth.instance
        .verifyPhoneNumber(
          phoneNumber: '+447123123456',
          verificationCompleted: (PhoneAuthCredential credential) {},
          verificationFailed: (FirebaseAuthException e) {
            print("Code  Failed 2");
            print(e);
          },
          codeSent: (String verificationId, int resendToken) {
            print("Code Send");
          },
          codeAutoRetrievalTimeout: (String verificationId) {},
        )
      );

Answer 1

Few of the possible reasons because of which it is not working might be-

1. You may not have enabled the sms-verification authentication in the firebase console.
2. Check whether you are connected to internet in emulator or actual device while testing.
3. Other possible reason can be be the emulator's android image. Try to test in some other modern image which support google play services.
