show component only if corresponding plugin is already loaded

[gennaro-tedesco]

I have a lualine component that shows a specific statusline containing a plugin variable; however such plugin isn't always loaded at startup (but rather lazy loaded on specific conditions). By introducing such statusline component, instead, the plugin is automatically loaded by lualine even if I specify the condition to only require if loaded already.

Essentially what I do is the following:

lualine.setup({
...
  sections = {
  .. 			
    {
      require("my-plugin").value
      cond = function()
        return package.loaded["my-plugin"] ~= nil
      end 
    },
  }
})

it seems that the condition package.loaded["my-plugin"] ~= nil is not evaluated before, rather require("my-plugin").value is executed anyway.

What is the recommended way to write such logic, namely to show plugin components only upon conditions that said plugins are already loaded (otherwise it would defy the entire concept of lazy loading)?
