Code before:
        row_heights: Optional[Iterable[Optional[float]]] = None,
        col_widths: Optional[Iterable[Optional[float]]] = None,
        flow_order: str = "rd",

    ) -> "Mobject":
        """Arrange submobjects in a grid.

        Parameters
        ----------
        rows
            The number of rows in the grid.
        cols
            The number of columns in the grid.
        buff
            The gap between grid cells. To specify a different buffer in the horizontal and
            vertical directions, a tuple of two values can be given - `(row, col)`.
        cell_alignment
            The way each submobject is aligned in its grid cell.
        row_alignments
            The vertical alignment for each row (top to bottom). Accepts the following characters: `"u"` -
            up, `"c"` - center, `"d"` - down.
        col_alignments
            The horizontal alignment for each column (left to right). Accepts the following characters `"l"` - left,
            `"c"` - center, `"r"` - right.
        row_heights
            Defines a list of heights for certain rows (top to bottom). If the list contains `None`, the corresponding row will fit its height automatically based
            on the highest element in that row.
        col_widths
            Defines a list of widths for certain columns (left to right). If the list contains `None`, the
            corresponding column will fit its width automatically based on the widest element in that column.
        flow_order
            The order in which submobjects fill the grid. Can be one of the following values:
            "rd", "dr", "ld", "dl", "ru", "ur", "lu", "ul". ("rd" -> fill rightwards then downwards)

        Returns
        -------
        Mobject
            The mobject.

        NOTES
        -----

        .. note::
            If only one of :code:cols and :code:rows is set implicitly, the other one will be chosen big
            enough to fit all submobjects. If neither is set, they will be chosen to be about the same,
            tending towards :code:cols > rows (simply because videos are wider than they are high).

        .. note::
            If both :code:`cell_alignment` and :code:`row_alignments` / :code:`col_alignments` are
            defined, the latter has higher priority.
