O middleware não precisa ser feito para o FastAPI ou Starlette para funcionar, desde que siga a especificação ASGI.

No geral, os middlewares ASGI são classes que esperam receber um aplicativo ASGI como o primeiro argumento.

Então, na documentação de middlewares ASGI de terceiros, eles provavelmente dirão para você fazer algo como:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

        return null;
    }

    @Override
    public void fetchFirst(int fetchSize) {
        _fetchScopeEffective = true;
        if (fetchSize < 0) {
            String msg = "Argument[fetchSize] should be plus: " + fetchSize;
            throw new IllegalArgumentException(msg);
        }
        _fetchStartIndex = 0;
        _fetchSize = fetchSize;
        _fetchPageNumber = 1;

        return null;
    }

    @Override
    public void fetchFirst(int fetchSize) {
        _fetchScopeEffective = true;
        if (fetchSize < 0) {
            String msg = "Argument[fetchSize] should be plus: " + fetchSize;
            throw new IllegalArgumentException(msg);
        }
        _fetchStartIndex = 0;
        _fetchSize = fetchSize;
        _fetchPageNumber = 1;

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).
* Any sequence of arguments that should be passed to the task function in order (`email`).
* Any keyword arguments that should be passed to the task function (`message="some notification"`).

## Dependency Injection { #dependency-injection }

     * @param args the array of objects to be passed as arguments to the constructor invocation
     * @return a new object created by invoking the constructor
     * @throws InstantiationRuntimeException if the class declaring the constructor is abstract
     * @throws IllegalAccessRuntimeException if the number of actual and formal parameters differ, if primitive arguments cannot be converted, or if the class is related to enums

     * If that matcher returns {@code false}, then the directory will definitively not contain
     * the paths selected by the matcher given in argument to this method.
     * In such case, the whole directory and all its sub-directories can be skipped.
     * In case of doubt, or if the matcher given in argument is not recognized by this method,
     * then the matcher returned by this method will return {@code true}.
