我在flutter应用程序中使用image_picker 0.8.5包进行图像上传。
下面的代码在android模拟器中运行良好，但ios模拟器不显示图像。

List images = [[]];
  final _picker = ImagePicker();
  Future<void> _openImagePicker() async {
    final XFile? pickedImage =
        await _picker.pickImage(source: ImageSource.gallery);
    if (pickedImage != null) {
      setState(() {
        images[index].add(pickedImage);
      });
    }
  }

.......

Expanded(
              child: SingleChildScrollView(
                scrollDirection: Axis.horizontal,
                child: Row(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    PhotoCarouselWidget(
                      ImageList: images[subindex],
                      onRemove: (int) {
                        setState(() {
                          images[subindex].removeAt(int);
                        });
                      },
                    ),
                  ],
                ),
              ),
            ),

在ios模拟器控制台，我可以得到以下错误，当我点击图像拾取器按钮。

VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: PlatformException(multiple_request, Cancelled by a second request, null, null)

iOS模拟器是iPhone13（iOS15.4）。
请帮助我修复这个错误，在ios模拟器中显示图像。
