I'm trying to get initial state in the same format as onStateChange prop provides in NavigationContainer. onStateChange doesn't fire on initial render. In the example below, I managed to get state when navigating between screens, but not on the first one. Any ideas?

export default function App() {
  const [pageState, setPageState] = React.useState();

  return (
    <NavigationContainer onStateChange={(state) => setPageState(state)}>
      <RootNavigation />
    </NavigationContainer>
  );
}
