Hi @suhailbilalw,

I tried running your project locally to test the integration, but unfortunately, I wasn’t able to. Have you been able to run the project locally on a real device?

Hello @paulperez-dev, Could happen because several files in the project are manually modified and app branch is the main branch. But if you will create a new fresh project, I'm sure facebook login will not work on android. flutter_facebook_auth library author has mentioned the issue in his documentation, saying it needs additional configuration. Please go through the documentation once as well.

@paulperez-dev Right now flutterflow is only including "facebook_app_id" in strings.xml but according to what documentation tells flutterflow should add second string "facebook_client_token" as well. That fixes the issue probably.

Hi @suhailbilalw,

Thanks for the information. I'm looking into this.
