Theme doom's content not vertically centered

[xfdj]

Describe the bug

My config:

return {
	"glepnir/dashboard-nvim",
	event = "VimEnter",
	config = function()
		require("dashboard").setup({
			theme = "doom",
		})
	end,
	dependencies = { { "nvim-tree/nvim-web-devicons" } },
}

The content goes to the top of my window, not the center of it.

Theme hyper is correct:

return {
	"glepnir/dashboard-nvim",
	event = "VimEnter",
	config = function()
		require("dashboard").setup({
			theme = "hyper",
		})
	end,
	dependencies = { { "nvim-tree/nvim-web-devicons" } },
}

I wonder if it is because the code below is missing in function theme_instance in lua/dashboard/theme/doom.lua:

    local size = math.floor(vim.o.lines / 2)
      - math.ceil(api.nvim_buf_line_count(config.bufnr) / 2)
      - 2
    local fill = utils.generate_empty_table(size)
    api.nvim_buf_set_lines(config.bufnr, 0, 0, false, fill)

I found the code in theme hyper's file. I don't know if it is a bug or a feature.

PS: Forgive my poor English.

I would also love to see this. Any updates?

I'm also interested in this issue, here is one small thing I noticed, maybe it will help:

I tried to add empty lines at the top of my logo in attempt to temporarily fix the centering issue, but it doesn't have any effect. But when I open some files and then use the Dashboard command to come back, then it looks correct.

Also it behaves differently in Alacritty and in Wezterm. In Alacritty, the empty lines helped.

You can inject spaces into the header itself to get this behavior
but it is kinda hacky

local api = vim.api

local function generate_empty_lines(size)
    local fill = {}
    for _ = 1, size do
        table.insert(fill, "")
    end
    return fill
end

local function center_header(header)
    local size = math.floor(vim.o.lines / 2)
        - math.ceil(#header / 2)
        - 2
    local fill = generate_empty_lines(size)
    return vim.list_extend(fill, header)
end

local header_content = {
  [[                                   ]],
  [[            header                 ]],
  [[                                   ]],
}

return {
    {
        'nvimdev/dashboard-nvim',
        event = 'VimEnter',
        config = function()
            require('dashboard').setup({
                theme = 'doom',
                config = {
                    header = center_header(header_content),
                    ...

I've made a PR #476 for this, but I think it needs more testing. Could someone please check it?
