result of chooseEntry is not correct

Hi,
when i use chooseEntry it return a ChooseEntryResult object but the fileEntries value of this object is always null.

    chrome.ChooseEntryOptions chooseEntryOptions =
        new chrome.ChooseEntryOptions(type: chrome.ChooseEntryType.OPEN_FILE);
    chrome.ChooseEntryResult chooseEntryResult =
        await chrome.fileSystem.chooseEntry(chooseEntryOptions);
    FileEntry fileEntry;

    print(chooseEntryResult.entry.isFile);
    print(chooseEntryResult.entry.name);

    Metadata meta = await chooseEntryResult.entry.getMetadata();

    print(meta.size);
    print(chooseEntryResult.fileEntries); // this line print null

    if (chooseEntryResult.fileEntries.length == 0) return;
    else {
      fileEntry = chooseEntryResult.fileEntries[0];
    }

If you have an idea, thanks.

after more research on that i have follow the chrome sample example here and it seams they cast an Entry to a FileEntry and when i did the same in dart i have :

NoSuchMethodError on the .slice()

    chrome.ChooseEntryOptions chooseEntryOptions =
        new chrome.ChooseEntryOptions(type: chrome.ChooseEntryType.OPEN_FILE);
    chrome.ChooseEntryResult chooseEntryResult =
        await chrome.fileSystem.chooseEntry(chooseEntryOptions);
    Entry entry = chooseEntryResult.entry;
    print(entry.isFile); // print true
    print(entry.name);

    Metadata meta = await chooseEntryResult.entry.getMetadata();
    print(meta.size);

    FileEntry fileEntry = (entry as FileEntry);
    File file = await fileEntry.file();
    Blob blob = file.slice(); // trig a NoSuchMethodError here

Wanted to update you that I haven't forgotten this issue, just in the middle of a very busy new year :) I hope to have time to address mid feb.

I was also having issues with chooseEntry. I looked into it, and I'm fairly certain it's a bug in the original JavaScript implementation. I ran the following in the console.

chrome.fileSystem.chooseEntry(function(a,b){console.log(a);console.log(b);});
// Returns a FileEntry for a, and undefined for b.

chrome.fileSystem.chooseEntry({acceptsMultiple: true},
    function(a,b){console.log(a);console.log(b);});
// Returns an array of FileEntry for a, and undefined for b.

chrome.fileSystem.chooseEntry({acceptsMultiple: false},
    function(a,b){console.log(a);console.log(b);});
// This also allows selection of multiple files, and is the same as the previous.

Also, I looked into the NoSuchMethodError. In src/files.dart File isn't implemented, so the underlying JsObject is cast to a File from dart:html. However, as far as I can tell the File from dart:html no longer implements JsObject so it doesn't work.
