Future<void> main() async {
  // Get some folder you would like to analyze.

  // Root folder path is used to resolve relative file paths.
  const rootFolder = 'projectRoot';

  const config = LintConfig(

  const analyzer = LintAnalyzer();

  final result =
      await analyzer.runCliAnalysis(foldersToAnalyze, rootFolder, config);

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

  // Now pass collected analysis reports from runner to reporter and that's it
  await analyzer
      .getReporter(name: 'console', output: stdout, reportFolder: '.')
      ?.report(result);

  // 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
