You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: structure.rb
    path of file: ./repos/vets-api/modules/appeals_api/app/services/appeals_api/pdf_construction/supplemental_claim/v2
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'common/file_helpers'

module AppealsApi
  module PdfConstruction
    module SupplementalClaim
      module V2
        class Structure
   
    
          def fill_text(pdf, attr, long_text_override: nil, length_for_override: SHORT_EMAIL_LENGTH)
            text = form_data.send(attr)

            return if text.blank?

            text = long_text_override if long_text_override.present? && text.length > length_for_override
            text_opts = form_fields.boxes[attr].merge(default_text_opts).merge(height: 13)

            whiteout pdf, **form_fields.boxes[attr]

            pdf.text_box text, text_opts
          end
