Generate nested routes

Interactive example

Apps accumulate dozens and then hundreds of routes over time.
Some of your routes make sense as top-level (global) routes.
For example, “/”, “profile”, “contact”, “social_feed” are all
possible top-level routes within your app. 
But, imagine that you defined every possible route in your
top-level Navigator widget. The list would be very long,
and many of these routes would 
be better handled nested within another widget.
