The suggestion is partially correct but overuses commas. Adding a comma after every closing bracket is unnecessary. Trailing commas should only be added where they help the Dart formatter preserve multi-line formatting.

Add a trailing comma only after the outermost closing brackets of widgets that should be formatted across multiple lines.

Avoid adding commas after inner brackets unless required for lists or complex widget structures.

something like this: home: Scaffold( body: Center( child: Text('Hello world'), ), ),

Unnecessary Commas: Adding commas after every bracket is excessive and not needed unless dealing with lists or maintaining complex layouts.
