i want run this sample by VS code.

Try to run flutter pub upgrade. I
was facing the same problem and it worked

RouteSettings.copyWith was removed.

Just use

From:

RouteSettings newSettings = oldSettings.copyWith(name: 'new name');

To:

RouteSettings newSettings = RouteSettings(name: 'new name', arguments: oldSettings.arguments);
