[jpnobrega]

I played one game called free fire for mobile devices. There, when i click on enter with facebook, the app redirect me to facebook app for get some permissions, without request password, because, i was logged on facebook app on my device. It's possible create something like this using this package? or someone knows how do something like this?

Someone correct me if I'm wrong but you only obtain an access token using the plugin. The rest should be handled in your backend (you should send the access token to your oauth service and implement what's needed to use the Facebook API)
