Question

这是我要执行的简单代码：

    Directory docDirectory = await getApplicationDocumentsDirectory();
    String path = docDirectory.path;
    if (DEBUG) print ('Site_Status: Document path : '+path);
    File file = File('$docDirectory/${widget.site.name}/example.txt');
    file.writeAsString('123');//writeAsBytesSync(doc.save());

我得到的错误是：

    [VERBOSE-2:ui_dart_state.cc(157)] Unhandled Exception: FileSystemException: Cannot open file, path = '/Users/D/Library/Developer/CoreSimulator/Devices/03A681BC-846F-42A5-9489-4C596F6EC8F0/data/Containers/Data/Application/4AA8DB7A-CE63-45EB-8596-D4CEE6BC8926/Documents/Pinpad/example.txt' (OS Error: No such file or directory, errno = 2)

我正在使用path_provider插件。我也在iOS和Android上都收到此错误。

Answer 1

使用<div id="parent"> <span id="main"> <span>sdfsdfdfd </span> sdfdsfsdfdsafadsfasdfafdfsdfsdffsfsdfdsfdsf sdfsdaf sdfdsfa dsfsdfsd dsf dfas sdfdsfa dsfsdfsd dsfsdfsd dfs sdfsf </span> </div>而不是path

docDirectory

希望这会对您有所帮助。

Answer 2

就我而言，问题出在另一个库上。文件选择器当我删除这个库问题解决了，但结果。有。其他一些可能导致此问题的库。像 image_picker 或。 cached_network_image

希望 Flutter 团队能解决这个问题。

Flutter path_provider插件无法正常工作-（操作系统错误：无此类文件或目录，errno = 2）
