Can't use 'cd' command in Dart CLI application

I am working on a Dart CLI application. I've clonned Flutter project from git into a directory, now I want to get in this directory and run flutter pub get in it. But I am having error. Btw I'm using dcli package.

Here is my method:

  void _runFlutterPubGet(String path) {
    'cd $path'.run;
    'flutter pub get'.run;
  }

Here is the error:

Unhandled exception:
cd C:\Users\baran\Software\Self\use_template\bin\trial_app 
exit: 2
reason: Could not find cd on the path.

Just a follow-up.

I'm the author of dcli.

You should never use cd in any program.

I've written an article about it. https://dcli.onepub.dev/dcli-api/the-evils-of-cd

Where required, dcli functions take a working directory (as you found) and ideally you should pass an absolute path.

Just for information: cd is a internal command of the command shell interpreter cmd.exe. Therefore there is no cd.com/cd.exe, which you can call. When you start a shell like you do now (runInShell = true), you are able to submit the cd command as the shell interpreter takes over.

I've changed my code to this:

  void _runFlutterPubGet(String path) {
    run('flutter pub get', workingDirectory: path, runInShell: true);
  }

As @julemand101 stated. Solved problem. Thanks for the answer.
