Creating a Multi-Screen App Not Working

[mgecawicz]

I have been working for quite a few days now at making a messaging app through this starter. I am able to get one screen working fine with Firebase, but the trouble comes with using a StackNavigator to go to another screen. Using createStackNavigator always throws the error message ... "null is not an object (evaluating 'RNGestureHandlerModule.State')". This is a problem that has not been clearly mentioned very much as far as I can tell as most errors posted about on sites like StackOverflow do not refer to "null" but rather "undefined". This is really holding back my progress. Any thoughts?
