runLiveShellCommand function

Future<int?> runLiveShellCommand(String name, List<String> arguments, LiveRunner runner)

Runs the metro live command name with arguments on runner's session and returns its exit code.

name is a live command without its prefix (status, seed), a live:run action (route), or one of the project's live commands (app:seed_demo, or seed_demo when only one command has that name). Returns null when nothing has that name.

Implementation

Future<int?> runLiveShellCommand(
  String name,
  List<String> arguments,
  LiveRunner runner,
) async {
  String command = name.startsWith('live:') ? name.substring(5) : name;
  List<String> rest = arguments;
  if (command == 'run') {
    if (arguments.isEmpty) return null;
    command = arguments.first;
    rest = arguments.sublist(1);
  }

  final NyCustomCommand Function(List<String>)? create =
      _liveShellBuiltIns[command] ?? liveRunActions[command]?.create;
  if (create != null) {
    return (create(rest) as _LiveBuiltInCommand).runWith(runner);
  }

  final String? moved = liveCommandMoved(command, runner: runner);
  if (moved != null) {
    runner.output.error(moved);
    return 64;
  }

  final String? appCommand = resolveLiveAppCommand(
    command,
    LiveManifest.load(),
  );
  if (appCommand == null) return null;
  return runLiveCustomCommand(appCommand, rest, runner: runner);
}
