The Markdown View will showcase display of markdown file retrieved from Github repository as rich text format. Thanks to Flutter Markdown package did the heavy duty, it makes the work a lot easier than I thought.
A picture is worth a thousand words:-
If you are interested to reuse the source code of the screen, please check out the markdown_view branch of the git repository hosted at https://github.com/limcheekin/fluwix. Feel free to fork the repository and send me pull request.
I'd love to hear from you. :)
