FirebaseAuth does not contain a method called signInWithTwitter, if you want to sign in using twitter then you need to use the class TwitterAuthProvider

For example:

switch (result.status) {
  case TwitterLoginStatus.loggedIn:
    var session=result.session;
    final AuthCredential credential= TwitterAuthProvider.getCredential(
      authToken: session.token,
      authTokenSecret: session.secret
    );
    FirebaseUser firebaseUser=(await firebaseAuth.signInWithCredential(credential)).user;
    print("twitter sign in"+firebaseUser.toString());
    break;
  case TwitterLoginStatus.cancelledByUser:
    break;
  case TwitterLoginStatus.error:
    break;
}

Inside the getCredential you can add the authToken and authTokenSecret and then pass the variable as an argument to signInWithCredentials
