runCommand method

@override Future<int> runCommand(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 result = await super.runCommand(topLevelResults);

  logger.flush();

  return result ?? 0;
}
