npm install @react-navigation/stack

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

const Stack = createStackNavigator();

const HomeScreen = ({ navigation }) => {
  // 添加if语句判断条件
  if (condition) {
    // 导航到其他屏幕
    navigation.navigate('OtherScreen');
  }

  return (
    // 页面内容
  );
};

const OtherScreen = () => {
  return (
    // 其他屏幕的内容
  );
};

const App = () => {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="OtherScreen" component={OtherScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
};
