dispose method

@override void dispose()

Releases everything this controller owns. The page that created the controller calls this from its own State.dispose(); a subclass that adds its own notifiers overrides this and ends with super.dispose().

@override
void dispose() {
  codeFilterController.dispose();
  titleFilterController.dispose();
  codeController.dispose();
  titleController.dispose();
  registrationNumberController.dispose();
  nationalCodeController.dispose();
  representativeController.dispose();
  addressController.dispose();
  postalCodeController.dispose();
  phoneNumberController.dispose();
  sign1OwnerController.dispose();
  sign2OwnerController.dispose();
  super.dispose();
}
