class FactCheck(TLObject):  # type: ignore
    """Represents a `fact-check » <https://core.telegram.org/api/factcheck>`_ created by an independent fact-checker.

    Constructor of :obj:`~pyrogram.raw.base.FactCheck`.

    Details:
        - Layer: ``229``
        - ID: ``B89BFCCF``

    Parameters:
        hash (``int`` ``64-bit``):
            `Hash used for caching, for more info click here <https://core.telegram.org/api/offsets#hash-generation>`_

        need_check (``bool``, *optional*):
            If set, the ``country`` / ``text`` fields will **not** be set, and the fact check must be fetched manually by the client (if it isn't already cached with the key specified in ``hash`` ) using bundled `messages.getFactCheck <https://core.telegram.org/method/messages.getFactCheck>`_ requests, when the message with the factcheck scrolls into view.

        country (``str``, *optional*):
            A two-letter ISO 3166-1 alpha-2 country code of the country for which the fact-check should be shown.

        text (:obj:`TextWithEntities <pyrogram.raw.base.TextWithEntities>`, *optional*):
            The fact-check.

    Functions:
        This object can be returned by 1 function.
