Lemon Grab's questions

我遇到一个问题，当我使用堆栈并添加一个具有手势检测器的子项并将其放置在父窗口小部件之外时，使用定位它不再检测手势，如果有修复程序，请解释一下，谢谢。我针对该问题的代码：

...List<Widget>.generate(
            images.length,
            (index) {
              return Stack(
                clipBehavior: Clip.none,
                children: [
                  Container(
                    height: deviceWidth / 3.5,
                    width: deviceWidth / 3.5,
                    clipBehavior: Clip.antiAlias,
                    decoration: BoxDecoration(
                        borderRadius: BorderRadius.circular(10)),
                    child: GestureDetector(
                      onLongPressStart: (details) {},
                      onTap: () async {
                        var imageFile = await pickImage();
                        if (imageFile != null) {
                          images[index] = makeImage(
                              isPlaceholder: false,
                              imageData: await imageFile.readAsBytes());
                          setState(
                            () {},
                          );
                        }
                      },
                      child: images[index],
                    ),
                  ),
                  Positioned(
                    left: -10,
                    top: -15,
                    child: Container(
                      alignment: Alignment.center,
                      height: 30,
                      width: 30,
                      decoration: const ShapeDecoration(
                          shape: CircleBorder(), color: Colors.red),
                      child: InkWell(
                        splashColor: Colors.white,
                        onTap: () {
                          images.remove(images[index]);
                          setState(() {});
                        },
                        child: const IgnorePointer(
                            child: Icon(Icons.delete_forever)),
                      ),
                    ),
                  )
                ],
              );
            },
          ),
