Esses validadores personalizados são para coisas que podem ser verificadas **apenas** com os **mesmos dados** fornecidos na requisição.

### Entenda esse código { #understand-that-code }

O ponto importante é apenas usar **`AfterValidator` com uma função dentro de `Annotated`**. Sinta-se à vontade para pular esta parte. 🤸

Essa prática é tão comum que tem um nome: essas variáveis de ambiente são comumente colocadas em um arquivo `.env`, e o arquivo é chamado de "dotenv".

/// tip | Dica

Um arquivo começando com um ponto (`.`) é um arquivo oculto em sistemas tipo Unix, como Linux e macOS.

Mas um arquivo dotenv não precisa ter exatamente esse nome de arquivo.
