E o resto será manipulado pelo **FastAPI**.

Se você rodar a aplicação e ir até [http://localhost:8000/v1/](http://localhost:8000/v1/), você verá o retorno do Flask:

```txt
Hello, World from Flask!
```

E se você for até [http://localhost:8000/v2](http://localhost:8000/v2), você verá o retorno do FastAPI:

```JSON
{
    "message": "Hello World"
}

This would be typical after a user initiates a force refresh by a pull to refresh type action.

```java
    val urlIterator = cache.urls()
    while (urlIterator.hasNext()) {

### Troubleshooting

1. Valid cacheable responses are not being cached

      id: String?,
      type: String?,

  }

  /**
   * Process the next event. This will result in a single call to [Callback.onEvent] *unless* the
   * data section was empty. Any number of calls to [Callback.onRetryChange] may occur while
   * processing an event.

    if (!allowNulls) {
      for (Object element : contents) {

    // Test both escapers after modifying the builder.
