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"

  <Stack.Screen
