Answer 1

React Navigation v3:

Navigation.navigate now takes one object as the parameter. You set the stack name then navigate to the route within that stack as follows...

navigation.navigate(NavigationActions.navigate({
    routeName: 'YOUR_STACK',
    action: NavigationActions.navigate({ routeName: 'YOUR_STACK-subRoute' })
}))

Where 'YOUR_STACK' is whatever your stack is called when you create it...

  YOUR_STACK: createStackNavigator({ subRoute: ... })
