Implementation

@override
Future<void> run() async {
  final year = now.year;
  final args = ensureArgResults();
  final specificFile = args['license'];

  final file = specificFile is String
      ? await _findLicenseFile(specificFile)
      : await _findDefaultLicenseFiles();
  final contents = await file.readAsString();
  if (!_yearIsUpdated(contents)) {
    await file
        .writeAsString(contents.replaceFirst(_yearRegexp, year.toString()));
    printer.printSuccess(
      'Year on ${file.basename} file has been updated to $year',
    );
  } else {
    printer.println('File is already updated.');
  }
}
