FileSystem API not supported

Using this code:

import('dart:html');

void main() {   window.webkitRequestFileSystem(Window.TEMPORARY, 5 1024 1024, (DOMFileSystem fs) {     window.console.log('Got Filesystem');     fs.root.getDirectory('path', successCallback: (Entry e) {       window.console.log('Got directory $e.name');     }, errorCallback: (FileError e) {       window.console.error(e);     });   }); }

In Dartium, I get the "Got Filesystem" message, but getting a directory (or file) results in an UnsupportedOperationException:

Stack Trace: 0. Function: 'DirectoryEntryImplementation.getDirectory' url: '/b/build/slave/dartium-mac-full/build/src/xcodebuild/DerivedSources/Release/webkit/bindings/dart/dart/DirectoryEntryImplementation.dart' line:20 col:3  1. Function: '::function' url: 'http://127.0.0.1:3030/Users/jasonhall/dart/filesystem/filesystem.dart' line:7 col:25

When running the generated JS (generated with dart2js), I get an UncaughtReferenceError stating that the errorCallback is not defined:

Uncaught ReferenceError: errorCallback is not defined filesystem.dart.js:2879 $.dynamicFunction.DOMWindow nullCheckMethod $.dynamicBind bind $.main (anonymous function)

I suppose this is probably a known issue, but I figured I'd file this to track its progress. This might be considered a duplicate of Issue #1241 as well.

Fixed in Dartium. Still doesn't work in frog though. Stephen, could you please take a look?

There is also some issue with dart2js as well (note: This error showed up when podilvilov's change went in, but because there were multiple commits I am marking the test as skip rather than reverting the commit):

CONSOLE MESSAGE: line 7935: Uncaught ReferenceError: errorCallback is not defined Content-Type: text/plain Running /mnt/data/b/build/slave/web-chrome-linux/build/dart/tests/html/fileapi_test.dart

This may be the same as issue #4549. I.e. we might be passing a Dart has instead of a normal JavaScript object to getDirectory.

This test is being skipped. We should try it again. The test may have bugs in the use of expectAsync.

This appears to be working properly on the latest bits, I am updating the tests to run correctly.

FYI- the syntax for the latest bits is: window.webkitRequestFileSystem(Window.TEMPORARY, 5 1024 1024, (DOMFileSystem fs) {     window.console.log('Got Filesystem');     fs.root.getDirectory('path',       options: {'create': true },       successCallback: (Entry e) {         window.console.log('Got directory $e.name');       },       errorCallback: (FileError e) {         window.console.error(e);       });   });

Tests have been updated and are enabled.
