Optional path parameters

[adamsowinski]

Hello I have an admin area of my app that uses a bottom tabbar for navigation. I'm using a nested navigation for it and it works great (route '/admin/:bottomBarIndex/'). On one page I have two tabs that are placed below app bar. What I would like to achive is have a nested navigation route like this '/admin/:bottomBarIndex/:topBarIndex' where topBarIndex parameter would be optional cause it applies only for one bottomBarIndex. How to do it? It seems that with current setup only routes with two parameters are matched so for example: '/admin/2/1' and not '/admin/2'.

Path parameters are required. You can use query parameters for optional params. Or you can use redirection, e.g.

routes: [
  // fill in the default value for topBarIndex
  GoRoute(path: '/admin/:bottomBarIndex', redirect: (c,s) => '/admin/${s.params['bottomBarIndex']}/1'),

  // now you have both params
  GoRoute(path: '/admin/:bottomBarIndex/:topBarIndex', build: (c,s) ...,
]
