在我的Flutter Mac应用程序中添加沙盒功能之后，无法重命名/移动文件

Question

代码块：

 String originalPath = '/Users/dhavalkansara/Library/Containers/com.myapp.apps/Data/Library/Caches/encryption-decryption/dummy copy 8.pdf.txt';
    String newPath = '/Users/dhavalkansara/Documents/dummy copy 8.pdf';

  try {
     File file = File(originalPath);
     await file.rename(newPath);
     print('File moved successfully');
  } catch (e) {
    print('Error: $e');
  }

eRror：

快报：错误：PathaccessException：无法将文件重命名为 '/users/dhavalkansara/documents/dummy copy 8.pdf'，path = '/users/dhavalkansara/library/containers/com.myapp.apps/data/library/caches/cencryption-decryptimption/dummy 复制8.pdf.txt'（OS错误：不允许操作，ERRNO = 1）

我具有应用沙盒功能的设置：

Answer 1

Import'Dart：io';

void movefile（）async { 字符串原始路径='/users/dhavalkansara/library/containers/com.myapp.apps/data/library/caches/encryption-decryption/dummy/dummy copy 8.pdf.txt'; 字符串newPath ='/users/dhavalkansara/documents/dummy copy 8.pdf';

try {

File file = File(originalPath);

// Copy the file first, then delete the original.

await file.copy(newPath);
await file.delete();

print('File moved successfully');
} catch (e) {
print('Error: $e');
}

}
