I want to do the ill-advised and place both an onClick and onDoubleClick on the same element with each type of event resulting in a different action. Specifically on an image, click to advance to the next image, double-click to toggle fullscreen. Naturally I get two clicks followed by a double-click (though I understand that some browsers only fire one click before the double-click). I had thought to make it easy on myself and place each event into a buffer (List) - or rather to add the event.type string to a list, then, after a suitable elapse of time, say 250 or 300 milliseconds examine the

I try to do the following: var properties = ["height" , "width"]; for (var prop in properties){ div.style[prop] = otherdiv.style[prop]; } But dart doesn't seem to accept this bracket notation, is there any other way to access a property using a string in dart ?

I need to save microphone input to use later in an AudioElement. I do this to get microphone input: window.navigator.getUserMedia(audio: true).then((MediaStream stream) { # what should go here? }); What should I do to save the audio? There are many horrible stupid examples out there where you are able to play the current audio recording in the current browser window. Is there ever a use case for this. For video I can imaging that one want to build a Skype like application and have a preview window to see if you look stupid on the video, but audio ... I found one good post though: From

I realised that in current Dart SDK version 0.4.1.0_r19425 methods like setTimeout , setInterval , clearTimeout , clearInterval aren't part of Window class any more and they all moved to WorkerContext . Is there any documentation on how to use them now? Do I need to create a new instance of WorkerContext every time I want to use them? In addition to Timer mentioned by Chris, there is a Future-based API: var future = new Future.delayed(const Duration(milliseconds: 10), doStuffCallback); There is not yet direct support for cancelling a Future callback, but this works pretty well: var future =
