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().

Implementation

@override
void dispose() {
  minDebtFilterController.dispose();
  maxDebtFilterController.dispose();
  dueDateController.dispose();
  debtController.dispose();
  creditorController.dispose();
  paidController.dispose();
  penaltyController.dispose();
  descriptionController.dispose();
  super.dispose();
}
