Rails - a way to check the last line while using smarter_csv gem

I am using smarter_csv gem to parse a large CSV file on Heroku.

SmarterCSV.process(file_name, { chunk_size: 10, headers_in_file: false, user_provided_headers: user_provided_headers }) do |chunk|  chunk.each do |row|    # parse row  endend

Is there any way to check if the row is the last line?
