How do I nest navigators in React Navigation?

Nesting navigators in React Navigation allows you to create a more complex navigation structure. You can nest stack navigators inside tab navigators, for example.

Can you show me a code example of nested navigators?

Sure! Here's a simple example:

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

const Stack = createStackNavigator();
const Tab = createBottomTabNavigator();

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

function App() {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Home" component={HomeStack} />
        <Tab.Screen name="Settings" component={SettingsScreen} />
      </Tab.Navigator>
    </NavigationContainer>
  );
}

What if I want to pass parameters to the nested screens?

You can pass parameters using the navigation.navigate method. For example:

navigation.navigate('Details', { itemId: 86 });

Then, in your DetailsScreen, you can access it via route.params.itemId.
