FacebookAuthProvider class

This class should be used to either create a new Facebook credential with an access code, or use the provider to trigger user authentication flows.

For example, on web based platforms pass the provider to a Firebase method (such as signInWithPopup):

FacebookAuthProvider facebookProvider = FacebookAuthProvider();
facebookProvider.addScope('user_birthday');
facebookProvider.setCustomParameters({
  'display': 'popup',
});

FirebaseAuth.instance.signInWithPopup(facebookProvider)
  .then(...);

If authenticating with Facebook via a 3rd party, use the returned accessToken to sign-in or link the user with the created credential, for example:

String accessToken = '...'; // From 3rd party provider
FacebookAuthCredential facebookAuthCredential = FacebookAuthProvider.credential(accessToken);

FirebaseAuth.instance.signInWithCredential(facebookAuthCredential)
  .then(...);
