Nestednavigation , logout action

[Amerr]

Its a doubt rather than a issue , how the Logout action is handled in navigation reducer,

I checked code , where u reset using Navigation Action and again init with login routeName.

How does it work internally. i have usecase where

TabNavigator({
banner: {screen: banner},
login: {screen: login},
home: TabNav({
logout: { screen: logout },
eventListing: StackNav({
event: { screen: event }
})
})
})

let say my im in Logout screen , how do i update stateForLoggedOut using NavigationAction reset.
