Se você precisa de GraphQL, eu ainda recomendaria que você desse uma olhada no <a href="https://strawberry.rocks/" class="external-link" target="_blank">Strawberry</a>, pois ele é baseado em anotações de tipo em vez de classes e tipos personalizados.

Not all client code is compiled with NullAway.
Do not make a parameter `@Nullable` just to check and throw a `NullPointerException` when it is `null`. 

## Status

ACCEPTED

## Consequences

* Classes are forced to have consistent nullability annotations.
* IDE warnings become more accurate, reducing warnings fatigue.
* Public API nullability annotations become closer to reality.
