title: Reset stack after navigate to login screen
body: <p>I am making a react-native mobile app, and I have a navigation drawer with a logout button on it. I know how to navigate from there to the login screen, using <code>props.navigation.navigate('Login')</code>, but the problem is that if the user does this, they can still open the drawer from the Login screen and navigate back to one of the other screens, or press the back button on Android.</p>
  
  <p>I guess I could do a check on the Login screen if the user came from another page and then disable the open drawer button, but that seems kinda hacky. I was wondering if there is a correct way of doing this, perhaps to reset the stack upon arrival on the Login, I'm not sure.</p>
