Would be nice to have Facebook Share Dialog

Is your feature request related to a problem? Please describe.
I'm not sure about this, but I suspect that Facebook will require any app that uses the user_post permission to interact with the user's timeline. It says so here https://developers.facebook.com/docs/permissions#u
The user_posts permission allows your app to access the posts that a user has made on their timeline.
**Allowed Usage** Enable people to create physical or digital books or albums of their timelines, and to share memories from their timeline on Facebook or on other social apps.

Describe the solution you'd like
To implement a Facebook Share Dialog in the Native implementation of this plugin for both iOS & Android.

Describe alternatives you've considered
I am presently calling the share interface on the web (which uses the JavaScript SDK)
const navUrl = 'https://www.facebook.com/sharer/sharer.php?u=' + urlstring
let brow = this.iab.create(navUrl, "_blank", "location=true");

I'm not sure this will be allowed on a Native device.
