无法以抖动方式检索保存的图像(仅在iOS上可重现该问题) [英] Unable to retrieve saved image in flutter (issue reproducible only on iOS)

问题描述

我正在使用SQflite保存图像，当我从头开始重新启动应用程序时，我无法再次找到图像文件.

I'm saving the image using SQflite, when I restart app from scratch I couldn't locate the image file again.

下面是供您参考的代码.

Below is the code for your reference.

  File _storedImage;

  Future<void> _takePicture() async {
    final imageFile = await ImagePicker.pickImage(
      source: ImageSource.gallery,
      maxWidth: 600,
    );
    if (imageFile == null) {
      return;
    }
    setState(() {
      _storedImage = imageFile;
    });
    final appDir = await syspaths.getApplicationDocumentsDirectory();
    final fileName = path.basename(imageFile.path);
    final savedImage = await imageFile.copy('${appDir.path}/$fileName');
    widget.onSelectImage(savedImage);
  }

以下是例外情况详细信息，供您参考.

Below is the exception details for your reference.
