  // Store keeps reported issues in format-agnostic way
  final store = MetricsRecordsStore.store();

  // Analyzer traverses files and report its findings to passed store
  final analyzer = MetricsAnalyzer(store, config);

  // Runner coordinates analyzer and store
  final runner = MetricsAnalysisRunner(
    analyzer,
    store,
    foldersToAnalyze,
    rootFolder,
  );

  // Execute run() to analyze files and collect results
  await runner.run();

  // Now runner.results() contains some insights about analyzed code. Let's report it!
  // For a simple example we would report results to terminal

  // Now the reporter itself
  final reporter = ConsoleReporter(stdout);

  // Now pass collected analysis reports from runner to reporter and that's it
  await reporter.report(runner.results());

  // There is also JsonReporter for making machine-readable reports
  // HtmlReporter produces fancy html-documents with bells and whistles
  // And CodeClimateReporter produces reports that are widely understood by various CI tools
  // If none of these fits your case you can always access raw analysis info via results() method of runner and process it any way you see fit
