I'm trying to use the flutter_facebook_auth 3.3.2+2 package and the firebase_auth 1.0.3 to do the facebook login, I basically copy and paste the code from their doc https://facebook.meedu.app/#/firebase-auth
import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter_facebook_auth/flutter_facebook_auth.dart';
Future<UserCredential?> signInWithFacebook() async {
final LoginResult result = await FacebookAuth.instance.login();
if(result.status == LoginStatus.success){
// Create a credential from the access token
final OAuthCredential credential = FacebookAuthProvider.credential(result.accessToken!.token);
// Once signed in, return the UserCredential
return await FirebaseAuth.instance.signInWithCredential(credential);
}
return null;
}
I tried to login with it, but when it goes down to the code await FirebaseAuth.instance.signInWithCredential(credential);
It pops the error: E/flutter (23237): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: [firebase_auth/invalid-credential] The supplied auth credential is malformed or has expired. [ Remote site 5XX from facebook.com for VERIFY_CREDENTIAL ]
I've checked all the app id, app secret, callback url, package name are matching, I have no clues what did I do wrong. Please can anybody tell me what is happening?
There could be multiple reasons: Choosing wrong app type in Facebook console instead of "Build Connected Experiences"
