working on basic use of flutter. Navigation Rail does not seem to support sub menus or atleast I can't find how to do it. It is not a very important feature so I would push it to another day.
Next time I might work on the cover page (maybe some cool things I could do?) and work on what I could put for chapter1. Now I don't know how much one page can hold so that I could explore. I would like it to be more flexible (so I can investigate different subchapters within the chapter by moving through pages but I am not sure)
