I like the demoflexfold webapp. It is the best flutter web app that I have seen so far. I am waiting eagerly for when you'll open source its code. I noticed that the pages are not navigable from the system(browser address bar) . I have been reading about navigator 2.0 and the new page routing system. I think having it part of demoflexfold would serve as a great reference point for a feature rich flutter app.
