android - PlatformException(already_active, 图像选择器已经激活, null, null)

Question

我试图使用 multi_image_picker2 5.0.2包这是我的代码

Future<void> loadImageAssets() async {
    List<Asset> resultList = <Asset>[];
    String error = 'No Error Detected';
    try {
      resultList = await MultiImagePicker.pickImages(
        maxImages: 10,
        enableCamera: true,
        selectedAssets: images,
        cupertinoOptions: CupertinoOptions(
          takePhotoIcon: "chat",
          doneButtonTitle: "Fatto",
        ),
        materialOptions: MaterialOptions(
            actionBarColor: "#ffffff",
            allViewTitle: "All Photos",
            useDetailsView: false,
            selectCircleStrokeColor: "#000000",
            actionBarTitleColor: "#000000",
            statusBarColor: "#000000",
            backButtonDrawable: "#000000"),
      );
    } on Exception catch (e) {
      ScaffoldMessenger.of(context)
          .showSnackBar(SnackBar(content: Text(e.toString())));
      developer.log(e.toString());
      error = e.toString();
    }
    if (!mounted) return;
    setState(() {
      images = resultList;
      _error = error;
    });
  }

但抛出以下异常
