Fix : blank window after quitting the dashboard or typing window #21

Fixes : #21

that isnt a good fix. cuz this happens with all plugins that use volt. And only on the lazyvim dashboard idk why

it doesnt happen on nvchads dashboard

Yeah this wasn't a complete fix(more like a hack) , what I basically did is close the window if the buffer gets closed. I looked at the volt code for close it only closes the buffer using nvim_buf_delete but it never deletes the window it is attached to ,is it intended to do so? If yes , I think the bug arises when there is no open buffers other that the one created by volt , and closing the buffer forces it to open a new empty buffer.

Let me test what is different in NVChads dashboard that is preventing the bug

Edit: After looking at the Nvdash code and that of oil.nvim and alpha.nvim, I believe that the bug does not appear in nvchad is because the buffer opening and focus handling in better implemented in it, but other dashboard did not do that . I believe that the only way to fix that will be to change the implementation of volt's close function in some way to accommodate the different ways every plugin handles these buffers.

If you think this can be a valid path to solve it then I can try to research it a bit more and try some generalized solution for volt.

For now I suggest that the close_func property of the close function in volt can be used to give a custom behaviour to typr:

close_func = function()
      for _, win in ipairs(open_windows) do
        if api.nvim_win_is_valid(win) then
          api.nvim_win_close(win, true)
        end
      end
    end
