我报的是 errno = 1

压缩图片: /Users/duke/Downloads/bg.jpg
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FileSystemException: Cannot open file, path = '/Users/duke/Downloads/img_1664423934143.jpg' (OS Error: Operation not permitted, errno = 1)

img_1664423934143.jpg 这个图片是不存在的，估计是压缩完后存放的文件名。
我是用的macos。

这个问题已经解决了，由于我开发的是desktop，所以需要文件系统的权限，
在macos中找到文件：DebugProfile.entitlements
将配置部分改为如下即可：

<key>com.apple.security.app-sandbox</key>
	<false/>
	<key>com.apple.security.cs.allow-jit</key>
	<true/>
	<key>com.apple.security.network.server</key>
	<true/>

	<key>com.apple.security.network.client</key>
    <true/>
    <key>com.apple.security.files.user-selected.read-only</key>
    <true/>
    <key>com.apple.security.files.user-selected.read-write</key>
    <true/>
