@override Future<void> run()

Runs this command.

The return value is wrapped in a Future if necessary and returned by CommandRunner.runCommand.

Implementation

@override
Future<void> run() async {
  final PubspecSource source = buildSource(argResults!);
  if (argResults!.rest.isEmpty) {
    throw ArgumentError('No output directory provided.');
  }
  final String outputDir = argResults!.rest.last;
  print('Fetching pubspec files to "$outputDir"');

  final uris = await source.fetchPubspecUris();
  print('Found ${uris.length} pubspec files');
  print('Downloading pubspec files to $outputDir');
  for (final uri in uris) {
    final file = File('$outputDir/${uri.toString().hashCode}.yaml');
    if (!file.existsSync()) {
      final content = await source.fetchPubspecContent(uri);
      file.writeAsStringSync(content);
    }
  }
  print('Downloaded ${uris.length} pubspec files to $outputDir');
