If you are a lazyvim user and want to enable relative line numbers, first create a file for neo-tree.nvim if you don’t have already, under the plugins folder:

return {
  "nvim-neo-tree/neo-tree.nvim",
}

Next, we are going to update our config by addin an option with event handler to display relative line numbers when the neo-tree buffer becomes active:

return {
  "nvim-neo-tree/neo-tree.nvim",
  opts = {
    event_handlers = {
      {
        event = "neo_tree_buffer_enter",
        handler = function()
          vim.opt_local.number = true
          vim.opt_local.relativenumber = true
        end,
      },
    },
  },
}

Now, when you open the neo-tree, you should see the line numbers.
