class Settings:
    def __init__(self) -> None:
        self.greeting = "hello"


class Dependencies(Group):
    settings = providers.Factory(scope=Scope.APP, creator=Settings)


dispatcher = Dispatcher()
setup_di(dispatcher, Container(groups=[Dependencies], validate=True))


@dispatcher.message()
@inject
async def greet(message: Message, settings: typing.Annotated[Settings, FromDI(Dependencies.settings)]) -> None:
    await message.answer(f"{settings.greeting}, {message.from_user.first_name}")
