dart 有没有办法在Flutter with Tflite中实现批次分类？

我想迭代地对多幅图像进行分类，我用

Future pickImages() async {
final List<XFile>? images = await ImagePicker().pickMultiImage();
if (images == null) return;

images.forEach((image) async {
  print('- Name: ${image.path}');
  await runModel(image.path);
});

}

Future runModel(String imagePath) async {
var recognitions = await Tflite.runModelOnImage(
    path: imagePath,
    numResults: 1,
    threshold: 0.5,
    imageMean: 127.5,
    imageStd: 127.5,
    asynch: true // defaults to true
    );

print(recognitions);
await Future.delayed(Duration(seconds: 1));
setState(() {});

}

如果我只选择一个图像，一切运行正常，只要我继续选择多个图像，我得到以下错误：

PlatformException (PlatformException(Failed to run model, Interpreter busy, java.lang.RuntimeException: Interpreter busy

我已经尽力了，但还是没能解决这个问题。
如果您能建议如何对多个选定的图像（ImagePicker）进行推断，我将非常感激。
谢谢！

这对我很有效：
对于pickImage：

async {
final ImagePicker _picker = ImagePicker();
final pickedFile = await _picker.pickMultiImage();
List<XFile> xfilePick = pickedFile;
setState(
      () {
    if (xfilePick.isNotEmpty) {
      for (var i = 0; i < xfilePick.length; i++) {
        selectedImages.add(File(xfilePick[i].path));
      }
    }
  },
);

for (var i = 0; i < selectedImages.length; i++){
    await Future.delayed(const Duration(seconds: 1));{
      imageClassification(selectedImages[i]);
      await Future.delayed(const Duration(seconds: 1));
    }
  }}
