An alternative option that was discussed was to establish some kind of parent-child relationship between controllers:

final parent = WizardController(
  routes: {
    '/a': WizardRoute(builder: ...),
    '/b': WizardRoute(builder: (_) => Wizard(controller: child)),
    '/c': WizardRoute(builder: ...),
  },
)

final child = WizardController(
  parent: parent,
  routes: {
    '/1': WizardRoute(builder: ...),
    '/2': WizardRoute(builder: ...),
    '/3': WizardRoute(builder: ...),
  },
);
