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: track_current_request.rb
    path of file: ./repos/debugbar/lib/debugbar/middlewares
    
    the code of the file until where you have to start completion: module Debugbar
  class TrackCurrentRequest
    def initialize(app)
      @app = app
    end

    def call(env)
      Debugbar::Current.ignore = De
    
    def call(env)
      Debugbar::Current.ignore = Debugbar.config.ignore_request?(env)

      return @app.call(env) if Debugbar::Current.ignore?

      Debugbar::Current.new_request!(SecureRandom.uuid)

      res = @app.call(env)

      # TODO: Remove this if statement?
      # We check meta because the frontend doesn't support request without meta yet.
      # It might happen with ActionController::Live where the following code
      # will run BEFORE ActionControllerEventSubscriber.process_action is called
      if Debugbar::Current.request&.meta
        # filename = "#{Time.now.to_i}--#{Debugbar::Current.request.meta.dig(:params, :controller)}_#{Debugbar::Current.request.meta.dig(:params, :action).gsub('/', '_')}.json"
        # File.open(Rails.root.join('_requests', filename), "w") do |f|
        #   f.write(Debugbar::Current.request.to_json)
        # end

        RequestBuffer.push(Debugbar::Current.pop_request!)

        # TODO: Refactor has not having ActionCable might more common than I thought
        if Debugbar.connected? && defined?(ActionCable)
          data = RequestBuffer.all.map(&:to_h)
          ActionCable.server.broadcast("debugbar_channel", data)
        end
      end

      res
    end
