        .. describe:: str(x)

            Returns the value of the text input or an empty string if the value is ``None``.

    .. versionadded:: 2.0

    Parameters
    ------------
    label: :class:`str`
        The label to display above the text input.
    custom_id: :class:`str`
        The ID of the text input that gets received during an interaction.
        If not given then one is generated for you.
    style: :class:`discord.TextStyle`
        The style of the text input.
    placeholder: Optional[:class:`str`]
        The placeholder text to display when the text input is empty.
    default: Optional[:class:`str`]
        The default value of the text input.
    required: :class:`bool`
        Whether the text input is required.
    min_length: Optional[:class:`int`]
        The minimum length of the text input.
    max_length: Optional[:class:`int`]
        The maximum length of the text input.
    row: Optional[:class:`int`]
        The relative row this text input belongs to. A Discord component can only have 5
        rows. By default, items are arranged automatically into those 5 rows. If you'd
        like to control the relative positioning of the row then passing an index is advised.
        For example, row=1 will show up before row=2. Defaults to ``None``, which is automatic
        ordering. The row number must be between 0 and 4 (i.e. zero indexed).
