Why does android studio gives warning on variable not used even when I have clearly used it in

I have need annoyed with the warning from the android studio on me not using the defined variable but in actual I have used it. What can be issue ? is something wrong with my coding pattern ?


class CategoryProvider with ChangeNotifier {
  List<CategoryModel> _categories = [];
  int _currenPage = 1;
  int _lastPage = 1;
  int _perPage = 1;

  List<CategoryModel> getCategories() => [..._categories];

  void setCategories(List<CategoryModel> _records) {
    _categories = _records;
    notifyListeners();
  }

  Future fetchCategories() async {
    try {
      ApiCall().getData(categoriesApi).then((data) {
        if (data['status'] == 'success') {
          _currenPage = data['collection']['current_page'];

In the above code, we can clearly see that the _current_page is been defined and used in the fetchCategories function. then why is android studio crying for the same?

Above is just an example and many more such variable exist and I have issued warnings for all.

Any suggestions on how to solve this ?

_currenPage = data['collection']['current_page'];

This means that you are declaring the _currenPage variable you haven't used it anywhere. you can use it like print(_currenPage) or pass it in some function. hopes it helps!
