what is your mistake?
I have been trying to get my head arouind this as well. What I want to do is, be able to test Facebook login using a browser. If I understand correctly, ionic-native uses cordova-plugin-facebook4 to interface with Facebook SDK, but the TypeScript flavor of Ionic Native doesn’t expose the browserInit method which the underlying plugin does. I think it would great great if Ionic Native can provide a wrapper for the browser fallback as well. Makes developing and testing so much easier.
