parseGitHubUrl static method

Implementation

    normalized = normalized.substring('git@github.com:'.length);
    normalized = normalized.replaceAll(RegExp(r'\.git$'), '');

  // the leading `/`).

  final owner = segments[0];
  // Strip .git suffix if present.
  final repo = segments[1].replaceAll(RegExp(r'\.git$'), '');
