Describe the Bug

I successfully logged into my Facebook account, but I can't seem to get their email.

Expected Behavior

I expected my Flutter app to create a Firebase Auth user using the Facebook user's email address.

To Reproduce

Here is some of my code:

onPressed: () async {
  final LoginResult result = await FacebookAuth.instance.login();
  if (result.status == LoginStatus.success) {
    final OAuthCredential credential = FacebookAuthProvider.credential(result.accessToken!.token);
    final UserCredential userCredential = await FirebaseAuth.instance.signInWithCredential(credential);

    print("Email: ${userCredential.user?.email}");
  }
},

Relevant log output

Email: null

Edit: I added the email permission in the Meta Developers console and it worked.

Same, did you find a solution?

@manav-kasare @mycar98765 keep in mind that this plugin only connect with the native facebook sdk so when you get the user profile data you only are making a http request to the graph API. You need to go to your facebook developers console and check that you have the right options enabled to be able to get the email user.

@darwin-morocho @manav-kasare Sorry for the late reply. I checked and I selected the correct option. Here are the options I chose:

@darwin-morocho Any updates?

Sorry but this is not an issue of this plugin. You need to go to your Facebook developer console and check what options you need to enable to be able to get the user email.

Keep in mind of this plugin only makes a simple http request to the graph api to get the user profile data using the session access token.

Add permissions parameter in the code

try {
  final LoginResult result = await FacebookAuth.instance.login(
    permissions: ['email', 'public_profile'],
  );
