Stack Navigator：什么是堆栈导航器，React Native 中的堆栈导航

// Native Stack — 推荐实现
import { createNativeStackNavigator } from '@react-navigation/native-stack';

type RootStackParamList = {
  Home: undefined;
  Profile: { userId: string; name: string };
  Settings: undefined;
};

const Stack = createNativeStackNavigator<RootStackParamList>();

function AppNavigator() {
  return (
    <Stack.Navigator screenOptions={{ headerShown: true }}>
      <Stack.Screen name="Home" component={HomeScreen} />
      <Stack.Screen name="Profile" component={ProfileScreen} />
      <Stack.Screen name="Settings" component={SettingsScreen} />
    </Stack.Navigator>
  );
}

# 安装 React Navigation 依赖
npm install @react-navigation/native @react-navigation/native-stack
npm install react-native-screens react-native-safe-area-context

# 对于 iOS — 安装 pod
cd ios && pod install && cd ..

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

type RootStackParamList = {
  Home: undefined;
  Details: { itemId: number; title: string };
};

const Stack = createNativeStackNavigator<RootStackParamList>();

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="Home"
        screenOptions={{
          headerStyle: { backgroundColor: '#6200ee' },
          headerTintColor: '#fff',
          gestureEnabled: true,
        }}>
        <Stack.Screen name="Home" component={HomeScreen}
          options={{ title: '主页' }} />
        <Stack.Screen name="Details" component={DetailsScreen}
          options={({ route }) => ({ title: route.params.title })} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

type RootStackParamList = {
  Home: undefined;
  Product: { id: string; category: string };
  Checkout: { items: CartItem[]; total: number };
};

// 类型化屏幕
type ProductScreenProps = NativeStackScreenProps<RootStackParamList, 'Product'>;

function ProductScreen({ navigation, route }: ProductScreenProps) {
  const { id, category } = route.params;

  return (
    <View>
      <Text>商品 {id} — {category}</Text>
      <Button title="加入购物车"
        onPress={() => navigation.navigate('Checkout', {
          items: [{ id, quantity: 1 }],
          total: 99.99,
        })} />
    </View>
  );
}

// Tab Navigator 中的嵌套堆栈
const HomeStack = createNativeStackNavigator<HomeStackParamList>();

function HomeStackScreen() {
  return (
    <HomeStack.Navigator>
      <HomeStack.Screen name="Feed" component={FeedScreen} />
      <HomeStack.Screen name="PostDetail" component={PostDetailScreen}
        options={{ presentation: 'modal' }} />
    </HomeStack.Navigator>
  );
}

// 具有共享选项的屏幕组
<Stack.Navigator>
  <Stack.Group screenOptions={{ headerShown: true }}>
    <Stack.Screen name="Main" component={MainScreen} />
    <Stack.Screen name="About" component={AboutScreen} />
  </Stack.Group>
  <Stack.Screen name="Auth" component={AuthScreen}
    options={{ presentation: 'modal', headerShown: false }} />
</Stack.Navigator>
