Firebaseauth with Facebook login #100

Open samycodes opened 5 years ago

samycodes commented 5 years ago

Hey guys, I am trying to login Firebase with facebook.

I am using firebaseauth:0.7.0 and flutter_facebook_login:

Here is my function for facebook login:

  startFacebookLogin() async {
    var facebookLogin = FacebookLogin();
    var result = await facebookLogin
        .logInWithReadPermissions(['email', 'public_profile']);
    FacebookAccessToken myToken = result.accessToken;
    AuthCredential credential =
        FacebookAuthProvider.getCredential(accessToken: myToken.token);
    FirebaseUser firebaseUser =
        await FirebaseAuth.instance.signInWithCredential(credential);
    createProfile(user);
  }

Here I got this error:
