runCommand method

@override @mustCallSuper Future<T?> 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
@mustCallSuper
Future<T?> runCommand(ArgResults topLevelResults) async {
  if (enableAutoInstall &&
      !_reservedCommands.contains(topLevelResults.command?.name)) {
    // When auto installing, use error level to display messages.
    tryInstallCompletionFiles(Level.error);
  }

  return super.runCommand(topLevelResults);
}
