Add relative line numbers in neo-tree using Lazy in Neovim

Just starting to learn Neovim and I m struggling with something that might be a simple to fix for someone experienced.

Using LazyVim distribution for Neovim which internally use Lazy.nvim as plugin manager and uses neo-tree as one of the plugins.

I want to configure neo-tree plugin to show relative line numbers in its file explorer.

Using this and this as referance, I made a new file in plugins/neo-tree.lua with this as contents:

return {
  {
    "nvim-neo-tree/neo-tree.nvim",
      opts = {
        view = {
           relativenumber = true,
        },
    },
  },
}

Now after this, when I restart, I should see line number but I don't. What could go wrong here?

Note: When I m in the neo-tree buffer and i set number, I see line numbers.

There is no relativenumber option for the nvim-neo-tree/neo-tree.nvim plugin. You are confusing with the nvim-tree/nvim-tree.lua plugin (discussion about this option).

For the neo-tree.nvim plugin, you could enable relativenumber with Lazy via event_handlers:

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