Exercício

Não deu para tirar print pois uso o celular para rodar o app, mas é só colocar na frente do "home: ". Tive a ideia de aplicar nomes de personagens de um anime que eu gosto muito. Espero que gostem mesmo assim :)

Antes de colar esse Scaffold depois do "home: ", é preciso apagar todas as linhas que estão abaixo de home. Isso é, até os parenteses, colchetes e chaves
