 Error: The method 'signInWithPhoneNumber' isn't defined for the class 'FirebaseAuth'.
Try correcting the name to the name of an existing method, or defining a method named 'signInWithPhoneNumber'.

Ran into the same issue. I believe its been replaced:

final AuthCredential credential = PhoneAuthProvider.getCredential(
  verificationId: _verificationId,
  smsCode: _smsController.text,
);
final FirebaseUser user = await _auth.signInWithCredential(credential);
