run method

@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 rest = argResults!.rest;
  if (rest.isEmpty) throw CliError('usage: preset save <preset.json>');
  final file = File(rest.first);
  if (!await file.exists()) {
    throw CliError('preset file not found: ${rest.first}');
  }
  final preset = Preset.fromJson(
    (jsonDecode(await file.readAsString()) as Map).cast<String, dynamic>(),
  );

  final client = _apiClientFrom(argResults!);
  try {
    await client.savePreset(preset);
    stdout.writeln(
      'saved "${preset.id}" (${preset.steps.length} steps) — apply it '
      'anywhere with: preset apply ${preset.id} --label …',
    );
  } finally {
    client.close();
  }
}
