I have a Dart [client side only, polymer] web-app. So I cannot use dart.io. I would like to do this semi-pseudo (language/platform mix!) code:

  ..
  String str = "a load of text";
  File file = new File('C:\\folder\\test.txt');
  file.write(str);
  file.close();

or

  window.clipboard.copy(str);

so the user can paste it. I have used a TextAreaElement to put the string on (using textarea.value=str), and then the user can copy and paste it himself, but that's a bit naff.
Thanks
Steve

Sorry, you cannot write to files on the file system from a web app. The restriction is from browsers and their security model.

  • Thanks. I thought that was the case, but stackedit and other web apps export to local disk. I see httprequest (haven't used it). It looks like I need to use that, but I'd prefer an automatic copy to the clipboard. Still learning....!
