FLUTTER Get access to an app feature only if you share the app

I made an app in flutter and it has special features. I want my users to be forced to share my app with their friend via email or messenger or any similar messaging app. I found the flutter_share package that could be suitable for the application (https://pub.dev/packages/flutter_share#-readme-tab-).
But I am not sure how can I be sure when the user leaves the app he is going to share it?
Can you help me with some demo app that has mentioned features?

Can I integrate the facebook messenger into a native app?

I am trying to use the facebook messenger bot feature without leaving my app (ios/android) and without needing to code my own chat which supports all the messenger features (tiles to choose answers etc.)
Is there any possibility to have the user chat with someone on facebook without the need to use the actual messenger app?

Invite user to install an iOS App using Facebook sdk without FBWebDialogs

I have an iOS Bussiness app, which used Facebook to login. Now I have access to the friends list. Is there a way to send a request to a Facebook friend (who is currently not using app) to install my App. My app is Bussiness app category not the game.

How should my users invite their Facebook friends to use my web app?

We have an app where users interact in small private groups. We want to allow our users to invite their Facebook friends into a group. We previously posted a private link on a friend's timeline but Facebook disabled that last week: https://developers.facebook.com/roadmap/#february-2013
The apprequest dialog will not work as it is limited only to canvas and mobile applications:
Requests are only available for Desktop Canvas, iOS and Android apps. Accepting a request on Canvas will direct the user to the Canvas Page URL of the app that sent the Request. For native mobile apps, accepting the request will direct the user to the app on their device if installed or to the appropriate location (Apple App Store or Google Play) to download the app otherwise.

I was thinking of using Facebook Open Graph and creating an action and mention tagging, but that seems like a hack, and I dont think engagement will be as high.
What do you think the best way to do this is?
Thanks!
Use Send to invite them in a private message.

Send a message between application users

I want to write a facebook app in which I'll show a list of the people who gave permission to use the app.
Each user would be able to pick another user from the list and send them a message from the app.
Is there any facebook api call I can use? Or I have to develop a stand alone messaging system?
