在以下情况下禁用堆栈导航器中的initialRoute加载

import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName={null}>
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Details" component={DetailsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

function App() {
  const [isLoggedIn, setIsLoggedIn] = useState(false);

  useEffect(() => {
    // 模拟异步获取登录状态
    setTimeout(() => {
      setIsLoggedIn(true); // 假设用户已登录
    }, 1000);
  }, []);

  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName={isLoggedIn ? 'Home' : 'Login'}>
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Login" component={LoginScreen} />
        <Stack.Screen name="Register" component={RegisterScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}
