How to set browser tab title with route name in React Native

Question

currently in my app, the browser tab title is just the name of the screen. However I want to set the tab title to {APP_NAME} - {PAGE_NAME} . I am using a <Stack.Navigator/> and I know that you use the screenOptions to give a custom title, but I cannot access the route name.

<Stack.Navigator
        initialRouteName={Pages.HOME}
        screenOptions={{
          title: `MyAppName - ${route.name}`,
          header: ({ navigation, back, route }) => (
            <Navbar
              navigation={navigation}
              back={back}
              title={route.name}
              navigationOptions={[
                Pages.HOME,
                Pages.MY_MESSAGES,
                Pages.PROFILE_AND_ACCOUNT,
                Pages.MY_ACCOUNT,
                Pages.FAQ,
              ]}
              actions={[logoutAction]}
            />
          ),
        }}
      >

As you can see, the header param contains route , but I cannot/don't know how to get this into the title.

Any help would be appreciated, thanks.

You don't need to do this for every screen. You can customize the document title in NavigationContainer

<NavigationContainer
  documentTitle={{
    formatter: (options, route) =>
      `MyAppName - ${options?.title ?? route?.name}`
  }}
>
  {/* content */}
</NavigationContainer>

Though also if you need the route name in options as mentioned in docs:

<Stack.Navigator
  screenOptions={({ route }) => ({
    title: route.name,
  })}
