Lint Staged is not taking the process arguments

[theprantadutta]

From the docs,
--processes [int] limit the maximum processes can run at the same time.
but when I run this with
dart run lint_staged --process 1
this throws the following error
Unhandled exception:
FormatException: Could not find an option named "--processes".
#0 Parser._validate (package:args/src/parser.dart:324:7)
#1 Parser._handleLongOption (package:args/src/parser.dart:310:7)
#2 Parser._parseLongOption (package:args/src/parser.dart:271:12)
#3 Parser.parse (package:args/src/parser.dart:91:11)
#4 ArgParser.parse (package:args/src/arg_parser.dart:334:42)
#5 main (file:///C:/Users/prant/AppData/Local/Pub/Cache/hosted/pub.dev/lint_staged-0.5.1/bin/lint_staged.dart:20:32)
#6 _delayEntrypointInvocation. (dart:isolate-patch/isolate_patch.dart:295:33)
#7 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:184:12)
how can I actually limit the process here?
