I have the following code that update the yaml content:

final editor = YamlEditor(mppm.toString());
  editor.appendToList(['packages'], "*");
  print(editor);

Output is:

{name: mppm, packages: [packages/*, "*"]}

But I am curious how can I add this content back to the yaml file?

If I use the following code to update the yaml file. It just add it as a normal string without any proper formatting:

File("pubspec-output.yaml").writeAsStringSync(editor.toString());

You'll need to have the original String for the file, and then apply the edits from the YamlEditor
