The snippet for a StatefulWidget with animation controller generates a wrong dispose() impl #3971

Implementations of this method should end with a call to the inherited method, as in super.dispose().

class _SomeWidget extends StatefulWidget {
  const_SomeWidget({Key? key}) : super(key: key);

  @override
  State<_SomeWidget> createState() => _SomeWidgetState();
}

class _SomeWidgetState extends State<_SomeWidget>
    with SingleTickerProviderStateMixin {
  late AnimationController _controller;

  @override
  void initState() {
    super.initState();
    _controller = AnimationController(vsync: this);
  }

  @override
  void dispose() {
    super.dispose();
    _controller.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Container();
  }
}

@override
void dispose(){
  _controller.dispose();
 super.dispose();
}
