How to put FB_APP_ID as parameter?

[francisrod01]

I have some problems about this library in my RN project.

• Is there a way to add a Facebook AppID as FBLogin parameter?
• The main screen is blank now
• I have FacebookLite installed in my Genymotion emulator
• Why app crashes after click in FBLogin button is clicked?
