How do I animate React Navigation transitions using createBottomTabNavigator?

Question

I've spent the last day trying to find out how to implement a simple fade screen transition with react-navigation but I cannot find one way to make it work with a bottom-tab-navigator. Can someone help me out? I've read the docs extensively but animations only seem to be available with a stack navigator.

Can you make transitions work on this snack demo?

Just create an Animated.View and attach that to your screens.

const FadeHomeScreen = (props) => (
  <FadeInView>
    <HomeScreen {...props} />
  </FadeInView>
);

then use this for Tab.Screen

<Tab.Screen name="Home" component={FadeHomeScreen} />

and just add unmountOnBlur: true in the screenOptions

const screenOptions = {
    unmountOnBlur: true,
    headerShown: false,
};

<Tab.Navigator {...{ screenOptions }}>

You could also use react-native-reanimated to create <FadeInView /> component
