Retrieving email address in Polymer Firebase-auth element using Google Authentication

Using Firebase Auth I want to get the email from google login, so I need the realm email. How can I add this to the firebase-auth element? Is it in the parameters? If so, how? An example would be great.

This can be done by calling one of the <firebase-auth>

less open APIs.

<firebase-auth
    id="auth"
    provider="{{provider}}"
    app-name="[[appName]]"
    signed-in="{{signedIn}}"
    user="{{user}}"
    on-error="onAuthError"></firebase-auth>

Inside Element Polymer Definition ...



// Currently supported providers are 'google', 'facebook', 'github', 'twitter'
loginUsingProvider: function(name) {
    var provider = this.$.auth._providerFromName(name);
    // Twitter simple login doesn't have scopes.
    if (name != 'twitter') {
        provider.addScope('email');
    }
    this.$.auth.signInWithPopup(provider)
        .then(function(response) {
            // success
        }, function(error) {
            // failure
        })
        .catch(function(exception) {
            // Exception 
        });
}

This was done with polymerfire

version 0.9.4. Check your versions with bower install polymerfire

).

According to the docs, there is a property here which is a named object user

that:

On login, this property reflects the auth object of the firebase object.



This should contain the required information.
