Expo 路由器堆栈屏幕无法根据订单工作

Question

世博堆栈屏幕无法正常工作，首次加载时未根据首先加载的（选项卡）屏幕加载顺序获取加载登录页面。当我尝试首先通过更改屏幕顺序加载我的登录屏幕时，我无法更改它。我清除了捕获物，我做了一切可能的事情，请帮助我。这是我的_layout.tsx

import FontAwesome from '@expo/vector-icons/FontAwesome';
import { DarkTheme, DefaultTheme, ThemeProvider } from '@react-navigation/native';
import { useFonts } from 'expo-font';
import { SplashScreen, Stack } from 'expo-router';
import { useEffect } from 'react';
import { useColorScheme } from 'react-native';
import { RootSiblingParent } from 'react-native-root-siblings';
import SignInPage from './screens/Login';
export {
  // Catch any errors thrown by the Layout component.
  ErrorBoundary,
} from 'expo-router';

// export const unstable_settings = {
//   // Ensure that reloading on `/modal` keeps a back button present.
//   initialRouteName: '(tabs)',
// };

export default function RootLayout() {
  const [loaded, error] = useFonts({
    SpaceMono: require('../assets/fonts/SpaceMono-Regular.ttf'),
    ...FontAwesome.font,
  });

  // Expo Router uses Error Boundaries to catch errors in the navigation tree.
  useEffect(() => {
    if (error) throw error;
  }, [error]);

  return (
    <>
      {/* Keep the splash screen open until the assets have loaded. In the future, we should just support async font loading with a native version of font-display. */}
      {!loaded && <SplashScreen />}
      {loaded &&  <RootSiblingParent>
        <RootLayoutNav />
          </RootSiblingParent>}
    </>
  );
}

function RootLayoutNav() {
  const colorScheme = useColorScheme();

  return (
    <>
      <ThemeProvider value={colorScheme === 'dark' ? DarkTheme : DefaultTheme}>
        <Stack>
        <Stack.Screen name="Login"  options={{ title: 'Log in' }} />
        <Stack.Screen name="screens/Mylistings" options={{ title: 'Log in' }} />

        <Stack.Screen name="screens/Signup" options={{ title: 'Sign Up' }} />
       
        <Stack.Screen name="modal" options={{ presentation: 'modal' }} />
        <Stack.Screen name="(tabs)" options={{ headerShown: false }} />
        </Stack>
      </ThemeProvider>
    </>
  );
}

世博会首先按字母顺序对您的路线名称进行排序，然后将第一个项目（屏幕）显示为您的初始路线。 解决方法是从您的

_layout.tsx

导出以下内容

export const unstable_settings = {
  initialRouteName: 'your-route-name',
};
