Is there a way to see if a Screen/Route exists in a navigation stack for React Navigation v5?

Question

Depending on if a screen exists in a certain stack I need to be able to do different things in my code. I have tried my best but I haven't found anything on the matter. Is there an easy way to achieve this?

Answer 1

In v.6 :

const navigation = useNavigation();
const routes = navigation.getState().routeNames;

Answer 2

If you mean, you want to get all the routes inside the current navigator, then I think this will fix your problem.

const navigation = useNavigation();

const routes = navigation.dangerouslyGetState().routeNames;
