When using both: Stack Navigator and BottomTab Navigator how do I hide the bottom tab when inside a Stack Navigation Screen?

Question

I am having a Bottom Navigation with 2 Tabs so far (Home & Messages). When inside Messages I can press on a User to get navigated to the ChatScreen which is a Screen from the Stack Navigator. In that ChatScreen I want to hide the BottomTab. I know that it is possible to hide it by adding tabBarStyle: { display: "none" } to the <Tab.Screen /> but this doesn't work for the ChatScreen since it is not a Tab.Screen

          ),

Used solution by @Escaper from another question

useEffect(() => {
    navigation.getParent()?.setOptions({ tabBarStyle: { display: "none" }});
    return () => navigation.getParent()?.setOptions({ tabBarStyle: undefined });
  }, [navigation]);

You could use createNavigationContainerRef to check the current route name via the getCurrentRoute() function inside the component that creates the BottomTabNavigator and then use tabBarStyle conditionally as you have suggested.

This could look as follows.

import { createNavigationContainerRef } from "@react-navigation/native"

const ref = createNavigationContainerRef();

const Tab = createBottomTabNavigator();

export default function App() {
  const hide = "ChatScreen" === ref.current?.getCurrentRoute()?.name
   
  return (
    <NavigationContainer>
      <Tab.Navigator initialRouteName="Messages">
        <Tab.Screen
        name="Home"
        component={HomeStackScreen}
        options={{
          headerShown: false,
          tabBarLabel: 'Home',
          tabBarIcon: ({ color }) => (
            <Icon name="home" color={color} size={26} />
          ),
        }}
        />
        <Tab.Screen
        name="Messages"
        component={MessageStackScreen}
        options={{
          headerShown: false,
          tabBarLabel: 'Messages',
          tabBarIcon: ({ color }) => (
            <Icon name="chat" color={color} size={26} />
          ),
          tabBarStyle: { display: hide ? "none" : "flex" }
        }}
        />
      </Tab.Navigator>
    </NavigationContainer>
  );
}
