          Navigator.of(context).pushNamedAndRemoveUntil(
            '/three',
            (route) => route.settings.name == '/one',

}

Navigator.of(context).pushNamedAndRemoveUntil(
  '/three',
  (route) => route.settings.name == '/one',

제가 이런식으로 '/'이 아닌 '/one'으로 바꾸어 보았는데, route_three에서 pop()하면 one으로 가는게 아니라 그냥 검은 화면이 보여요. '/'은 잘 작동하고 main파일에서도 정확히 '/one'으로 잘 등록해 놓았는데 왜 작동이 안되는 걸까요??
