import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import Main from './src/Main'
import Sub from './src/Sub'

const Stack = createNativeStackNavigator();
export default function App() {
  return (
    <PaperProvider>
      <NavigationContainer>
          <Stack.Navigator initialRouteName="Main">
            <Stack.Screen name="Main" component={Main} />
            <Stack.Screen name="Sub" component={Sub} />
          </Stack.Navigator>
      </NavigationContainer>

ページ遷移

export default function Sub({ navigation }) {

import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import Main from './src/Main'
import Sub from './src/Sub'

const Tab = createBottomTabNavigator();

export default function App() {
  return (
    <PaperProvider>
      <NavigationContainer>
        <Tab.Navigator>
          <Tab.Screen name="Main" component={Main} />
          <Tab.Screen name="Sub" component={Sub} />
