I just follow Future signInWithFacebook() async { // Trigger the sign-in flow final LoginResult loginResult = await FacebookAuth.instance.login();

// Create a credential from the access token final OAuthCredential facebookAuthCredential = FacebookAuthProvider.credential(loginResult.accessToken.token);

// Once signed in, return the UserCredential return FirebaseAuth.instance.signInWithCredential(facebookAuthCredential); }

then FacebookAuth.instance.accessToken to get information to check expires

Your code works but it doesn't ensure that the login with Facebook was succesful please use a code like this

import 'package:firebase_auth/firebase_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);
  }

print(result.status);
    print(result.message)

  return null;
}

Check in your console if you are getting some error

Lanticee commented 5 months ago

I make one sample project here https://github.com/Lanticee/testfb

I do not use firebase... I just need facebook token

darwin-morocho commented 5 months ago

Have you followed this https://facebook.meedu.app/docs/5.x.x/macos ?

Lanticee commented 5 months ago

yes. i followed. and it work yestoday, after update macos or flutter today, it not work any more

I tried use await FacebookAuth.getInstance().accessToken!; it make macos app crash.

I try this FirebaseAuth auth = FirebaseAuth.instance;

User? user = FirebaseAuth.instance.currentUser;

app get crash too.

darwin-morocho commented 5 months ago

@Lanticee sorry but I am not able to reproduce the issue even using your example repo. Login with macOs was successful. The Only thing I do was add the KeySharing capability without any group and it works.

Also you can try the last version of this plugin to check if the error persists

tested on

 macOS (desktop) • macos  • darwin-arm64   • macOS 14.1.1 23B81
Lanticee commented 5 months ago

I tried sample project again.

I added key sharing flutter_secure_storage

FacebookAuth.instance.accessToken .then((value) => debugPrint(value!.token));

The error says that you are using ! on a null value witch is right of there is not an active session. That doesn't tell us what is the problem. Try running the example project of this repo and tell me if the error persists

Lanticee commented 5 months ago

yes, FacebookAuth.instance is not work now.

sorry but you don't provide the enough info about the problem. Plase be more clear. Also try with the example project of this plugin to check a right way to use this plugin

Lanticee commented 5 months ago

sorry, I tried to find more information, but I still do very less things. I change sample project, and found FaceBookAuth.instance.accessToken null after FacebookAuth.instance.login. I still can get accessToken from loginResult or facebookAuthCredential , just found FacebookAuth.instance.accessToken not work anymore. thx.

Please try with the example project inside this repo. As I said I have runned your example without any problem. I just removed the firebase auth and the groups inside the keychain capabilty due to I Just want to test the Facebook login. Also I noticed that in your login you have custom persmission keep in mind that all that permission must be enabled and authorized into your Facebook console

Lanticee commented 5 months ago

hi i remove some permissions. left permissions: const ["public_profile", "email","publish_video"],

it works now.

'pages_read_engagement', 'pages_manage_posts' make it run wrong. thx a lot
