React Native Auth Flows: Conditional Navigators
Think of your app as having two sets of maps: one for guests, one for members. React Navigation swaps the entire map when a user logs in, not just moves them. This is the key to preventing users from back-navigating to the login screen after.
Think of your app as having two separate sets of maps: one for guests (auth screens) and one for members (main app). React Navigation conditionally renders a different set of available screens based on login state. On app start, you check a stored token; if valid, you render the main app screens, otherwise you show the auth screens. The footgun is thinking you just "navigate" to home. Instead, you swap the entire navigation stack, which correctly unmounts the auth screens and fixes the back button behavior.
