How to exclude a specific buffer from the BufEnter autocmd group?

Question

I want to load a plugin when I enter a buffer, so I set this event to BufEnter. But when I start neovim, the plugin loads at the dashboard buffer. I want to exclude that buffer. How can I do it?

Update

I created the augroup in the init.lua file before lazy.nvim and set the plugin event to the new augroup, but when I enter neovim, I get this error:

Failed to setup handlers for Comment.nvim

...hare/nvim/lazy/lazy.nvim/lua/lazy/core/handler/event.lua:68: Invalid 'event': 'BufInit'

# stacktrace:
  - init.lua:65

Note

I changed the augroup name from NVIMCMPtGrp to BufInit.

The plugin unloads when I'm on dashboard, but it doesn't load when I enter a file

Answer 1

So I found a solution which is to use the BufRead event, which doesn't affect dashboard for some reason.

return {
   "your/plugin",
   event = "BufRead",
}

Answer 2

I would put a condition in the autocmd command:

For Startify I would do:

augroup NVIMCMP
autocmd!
autocmd BufEnter * if &filetype!=#'startify' | MyCommand | endif
augroup END

For Dashboard I would do:

augroup NVIMCMP
autocmd!
autocmd BufEnter * if &filetype!=#'dashboard' | MyCommand | endif
augroup END

Or is Lua variant:

local NVIMCMPtGrp = vim.api.nvim_create_augroup('NVIMCMPtGrp ', { clear = true })
vim.api.nvim_create_autocmd({"BufEnter"}, {group = NVIMCMPtGrp , pattern = '*', callback = function()
  if not (vim.bo.filetype == 'dashboard') then
    -- MyCommand
  end
end
})
