setState() called after dispose()

[mrizkynurfajrie]

Hi there,
i'm facing a error message "Another exception was thrown: setState() called after dispose(): _MultiSelectDropDownState#5f37b(lifecycle state: defunct, not mounted)" after open the page.

Here how i reproduce using this package.

MultiSelectDropDown Widget

            Expanded(
                child: MultiSelectDropDown<Object>(
                  padding: EdgeInsets.symmetric(horizontal: 4.w),
                  controller: brandMultiController,
                  hint: "Select Brand",
                  hintStyle: TextStyles.textStdBlack.copyWith(
                    color: AppColor.neutral.shade400,
                    fontSize: FontSizes.s12,
                  ),
                  fieldBorderRadius: Corners.lg,
                  fieldBackgroundColor: AppColor.neutral.shade200,
                  borderColor: brandOutlineColor,
                  boxHeight: 46.h,
                  dropdownHeight: 225.h,
                  selectionType: SelectionType.single,
                  singleSelectItemStyle: TextStyles.textStdBlack,
                  clearIcon: null,
                  searchEnabled: true,
                  searchLabel: "search",
                  searchBackgroundColor: AppColor.whiteColor,
                  searchHintStyle: TextStyles.textStdBlack.copyWith(
                    fontSize: FontSizes.s12,
                    color: AppColor.neutral.shade400,
                  ),
                  searchContentPadding: EdgeInsets.symmetric(
                    horizontal: 12.w,
                    vertical: 2.h,
                  ),
                  optionTextStyle: TextStyles.textStdBlack,
                  optionSeparator: Container(
                    height: 1,
                    width: Get.width,
                    color: AppColor.neutral.shade300,
                  ),
                  options: brandOption,
                  onOptionSelected: onBrandOptionSelected,
                ),
              ),

Declare MultiSelectDropDown Controller

var brandMultiController = List<MultiSelectController<Object>>.empty(growable: true);

I do insert MultiSelectController into a growable List because it could be multiple MultiSelectDropDown widget with the same type/options.

Set Option

                                                    brandOption: controller
                                                        .listSelectedBrand
                                                        .map((item) {
                                                      return ValueItem(
                                                        label: item.brandName!,
                                                        value: item.brandId,
                                                      );
                                                    }).toList(),

And I have a required condition after an option selected

                                                    onBrandOptionSelected:
                                                        (brand) {
                                                      controller
                                                          .categoryMultiController[
                                                              index]
                                                          .setOptions(
                                                        controller
                                                            .listSelectedCategory
                                                            .map((item) {
                                                          return ValueItem(
                                                            label: item
                                                                .description!,
                                                            value: item.id,
                                                          );
                                                        }).toList(),
                                                      );
                                                    },

But after the code run, just like this error doesn't impact anything to how this widget works, everything's going very well.
Is it just a bug, or maybe something happen but i don't aware about that?

For now i'm using the latest version of this package.
