Pay attention to the `__init__` method used to create the instance of the class:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...it has the same parameters as our previous `common_parameters`:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8] *}

Those parameters are what **FastAPI** will use to "solve" the dependency.

In both cases, it will have:

O fator principal para uma dependência é que ela deve ser "chamável"

Um objeto "chamável" em Python é qualquer coisa que o Python possa "chamar" como uma função

Então se você tiver um objeto `alguma_coisa` (que pode *não* ser uma função) que você possa "chamar" (executá-lo) dessa maneira:

```Python
something()
```

ou

```Python

But if you want to **stream pure binary data** or strings, here's how you can do it.

/// info

Added in FastAPI 0.134.0.

///

## Use Cases { #use-cases }

You could use this if you want to stream pure strings, for example directly from the output of an **AI LLM** service.

You could also use it to stream **large binary files**, where you stream each chunk of data as you read it, without having to read it all in memory at once.
