runCliAnalysis method

Future<Iterable<UnusedFilesFileReport>> runCliAnalysis(Iterable<String> folders, String rootFolder, UnusedFilesConfig config, { String? sdkPath, })

Returns a list of unused files reports for analyzing all files in the given folders. The analysis is configured with the config.

Implementation

      _logger?.printConfig(unusedFilesAnalysisConfig.toJson());
    }

    // Files matched by the excludes are not reported, but they are still
    // analyzed for imports: generated code is often the only importer of
    // a hand written file.
    final filePaths = getFilePaths(folders, context, rootFolder, const []);
