undefined 不是一个对象（评估route.routeName）

when update the expo from (16.0.0) to (24.0.0) and react navigation from (git+https://github.com/react-community/react-navigation.git https://github.com/react-community/react-navigation.git) to (^1.0.0-beta.21) version, this error occured

终于知道如何解决这个问题了无证的抽屉导航器配置：

drawerOpenRoute: 'DrawerOpen',
drawerCloseRoute: 'DrawerClose',
drawerToggleRoute: 'DrawerToggle'
