Share post function is not working due to no Deep Linking of the app

Prerequisites

• I am running the latest version
• I checked to make sure that this issue has not already been filed

Expected Behavior

When you click/tap on the share icon, a modal opens up which allows you to share the post with its sharing URL and message.

Current Behavior

The current behavior only involves sharing a message when the share icon is clicked.

Steps to Reproduce

1. Launch the app
2. Go to Home Screen
3. Click on the share button

Proposed Solution

Implementing deep linking in the app using Firebase (more specifically Firebase Dynamic Links), which allow users to share links to specific screens or components i.e. posts of the Go-social app.
