Add custom user attribute using plugin

[vijay kumavat]

Hi Team NodeBB,

I am trying to create plugin to add one set image/icon field in the user setting page (user/username/settings) and this value display after user name in topic list page.

var Plugin = {};

console.log('outside - called properly');

Plugin.addCustomFields = function(hookData, callback) {

  console.log('Custom Field function is called properly');
   // Add your custom fields to the `fields` object here

   hookData.custom_field_1 = {
      type: 'text',
      required: true,
      title: 'Custom Field 1'
   };

};

module.exports = Plugin;

could you please guide me which method i need to use and for image/icon field how to write filed attribute?
