Simple named route navigation that unofficially addresses Flutter issue 11655 ("build needlessly called for non-current screens lower on stack").

I consider issue 11655 to be the single biggest problem with the Flutter widget build mechanism; it really bothers me so I felt compelled to roll my own solution.

THIS PACKAGE ISN'T FOR EVERYONE. I prefer the navigation approach implemented herein but it's non-standard.

Warning: This package is an active proof of concept--under active development--and may change drastically at any time.

Simplifications #

  • for simplicity of development, navigation is static
  • don't need to pass context
  • class named 'Nav' instead of 'Navigation' because it's shorter

Limitations #

  • since static, can't have multiple instances
  • doesn't work with showDialog() return values
  • doesn't work with Hero widget

Features #

  • backButtonCaption with callback function

TODO #

  • use generics for arguments: either Object (standard) or Map (my preference)
  • force redraw entire tree (not sure if possible)
  • pop all the way out of application (configure yes/no)
  • test: hot reload doesn't erase stack
  • solve: object vs. named route problem
  • pass in trace flag to constructor
  • return values? (friends showDialog... pop(return))
