How do you pass data with Navigator.push and return data with Navigator.pop?
Tests imperative navigation and async result patterns. Strong answer: push via MaterialPageRoute with constructor args; await the Future from Navigator.push; pop with Navigator.pop(context, result). Red flag: using global state instead of the Future result.
Tests your grasp of Flutter's imperative navigation stack and async result propagation. A strong answer hits four things in order: first, pass data forward by injecting it into the target widget's constructor inside MaterialPageRoute; second, await Navigator.push since it returns a Future that resolves when the route is popped; third, return data by calling Navigator.pop(context, result) in the child; fourth, handle null safety and type the Future.
