runCommand method

  1. @override
Future<int?> runCommand(
  1. ArgResults topLevelResults
)

Runs the command specified by topLevelResults.

This is notionally a protected method. It may be overridden or called from subclasses, but it shouldn't be called externally.

It's useful to override this to handle global flags and/or wrap the entire command in a block. For example, you might handle the --verbose flag here to enable verbose logging before running the command.

This returns the return value of Command.run.

Implementation

@override
Future<int?> runCommand(ArgResults topLevelResults) async {
  final command = topLevelResults.command;
  final runCommand = commands['run'];
  if (command?.name == 'run' &&
      command!.command == null &&
      command.rest.isEmpty &&
      runCommand is RunCommand) {
    runCommand.printUsage();
    return 0;
  }
  return super.runCommand(topLevelResults);
}
