How to dispose a text editing controller in flutter?

   TextEditingController titleC = TextEditingController();
   TextEditingController detailsC = TextEditingController();
// in dispose how can in dispose or clear my controller after submitting

   @override
   void dispose() {
   titleC.clear();
   titleC.dispose();
   detailsC.clear();
   detailsC.dispose();
   super.dispose();
 }

// for TextEditingController create:
final TextEditingController _emailController = TextEditingController();

// for TextEditingController dispose:
@override
  void dispose() {
    /* Discards any resources used by the object. After this is called,
    the object is not in a usable state and should be discarded
    (calls to addListener will throw after the object is disposed) */
    _emailController.dispose();
    super.dispose();
  }
