    Parameters
    ----------
    label: :class:`str`
        The label of the text input
    style: :class:`TextInputStyle`
        The style of the text input.
        By default, the style is ``TextInputStyle.short``, a one line
        input, but you can use ``TextInputStyle.paragraph``, a multi line
        input.
    custom_id: Optional[:class:`str`]
        The ID of the text input that get received during an interaction.
    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).
    min_length: Optional[:class:`int`]
        The minimal length of the user's input
    max_length: Optional[:class:`int`]
        The maximal length of the user's input
    required: Optional[:class:`bool`]
        If ``True``, the user cannot send the form without filling this
        field.
    default_value: Optional[:class:`str`]
        The value already in the input when the user open the form.
    placeholder: Optional[:class:`str`]
        The text shown to the user when the text input is empty.
