HI @ronnyhartenstein this is great, I'm trying to use this gist for a sample app I'm building but I can't get it to work. I'm getting this error

ExceptionsManager.js:63 setup(...): A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object.

so far I'm using your code, and then I'll try to make my modifications.

Do you know what's going on or what am I missing here?

I removed the wrapped function setup and at the end I'm export Root class, I'm learning react-native/react so I'm like

at least it's working, if I'm doing something wrong please advice. Thanks again.

@ronnyhartenstein This is excellent. Clean, straightforward and flexible. I'm wondering why it isnt more widely accepted as a suitable solution? Have you found any shortcomings i.e. deep linking, navigating based on push notification payloads (after verifying they are logged in), etc? Thanks again!

how would you logout from the MainNavigator and redirect to the Login screen found in the OnboardingNavigator using redux?

Sometimes I am getting weird errors when transitioning between screens this way. Had to add setTimeout which is beyond hackish
