Esse código abaixo é o código do arquivo com as screens

`import { createStackNavigator } from "@react-navigation/stack";

import Boasvindas from '../pages/boas-vindas'; import Boasvindas2 from '../pages/boas-vindas2'; import Boasvindas3 from '../pages/boas-vindas3'; import Login from "../pages/login"; import Cadastro from "../pages/cadastro";

const Stack = createStackNavigator();

export default function Routes (){ return( <Stack.Navigator> <Stack.Screen name = "Boasvindas" component={Boasvindas} options={{headerShown: false}} />

  <Stack.Screen
    name = "Boasvindas2"
    component={Boasvindas2}
    options={{headerShown: false}}
  />
  
  <Stack.Screen
    name = "Boasvindas3"
    component={Boasvindas3}
    options={{headerShown: false}}
  />
  
  <Stack.Screen
    name = "Login"
    component={Login}
    options={{headerShown: false}}
  />
  
  <Stack.Screen
    name = "Cadastro"
    component={Cadastro}
    options={{headerShown: false}}
  />
</Stack.Navigator>

); }`

Enquanto esse é o código da página que contém o navigation Container

`import React from "react"; import { StatusBar } from "react-native";

import { NavigationContainer } from "@react-navigation/native"; import Routes from "./src/routes";

export default function App(){ return( ) }
