Post Hierarchy – Single screen in React Native to display post hierarchy

We are a startup and developed an app which enables users to publish posts, show/display posts to all users and allows to share these posts.
This project is to develop a single screen that will display the published posts and shared posts in hierarchy (i.e. parent – child relation). Published post will be parent and number of shares will be child.

We expect a single screen designed and developed in React Native. Document has more details. This single screen will be integrated in our existing app.
