def get_user_full_name(event_from_user: User) -> str:
    return event_from_user.full_name


@router.message()
async def _(message: Message, full_name: Annotated[str, Depends(get_user_full_name)]) -> None:
    await message.answer(f'Hi {full_name}')


def main() -> None:
    logging.basicConfig(level=logging.INFO)

    bot = Bot(token=getenv('BOT_TOKEN'))

    dp = Dispatcher()
    dp.include_router(router)
    dp.message.middleware(DIMiddleware())  # register Dependency Injection middleware
    dp.run_polling(bot)

Details

It is inspired by FastAPI.

If you define a normal def, your function will be called in a different thread.
