Does dart support es6 Proxy? I couldnt find the information in the official documentation. Even searching in google didnt give me any results.
The reason im asking:
Im trying to detect when a certain property changes. Similar to C# INotifyPropertyChanged.
https://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged(v=vs.110).aspx
The short answer: not directly.
As Gunter mentioned, the observable package can be used to accomplish things that look like INotifyPropertyChanged from .NET.

I found that there are two ways to create a web3 instance.
this comes from the official doc:
new Web3(Web3.givenProvider)
most people use like this:
new Web3(window.ethereum)
So may i know which way should we choose? And what is the difference between them?
I think window.ethereum is generally for frontend projects and the other is for backend projects. I believe that window.ethereum is a property that MetaMask and similar browser plugins will inject, but obviously aren't available in node.js because there's no window object.
It's possible that some node library is creating a window object but I'm not aware of any.
I have started a crash course of IndexDB API. I have heard from the author that the API is a little bit confusing. Primarily, as we have been working with the promise pattern as this API doesn’t use this pattern. Secondary, there are different wrappers, one of them seems is from Github author’s personal library so I suppose he have created it.
However looking for a different flavor, I found this one: http://dexie.org/. Also supports the Promise pattern. See http://dexie.org/docs/Promise/Promise, http://dexie.org/docs/API-Reference#query-items . It seems “promising”.
Also I found that the IndexDB 2.0 API was created post the video time. It is already being supported since beginning of 2017. From a Mozilla developer, I found since Firefox 51 (Jan 2017) it is already there. And he wrote what’s the differences among 1 and 2 versions https://hacks.mozilla.org/2016/10/whats-new-in-indexeddb-2-0/
So my question is if at this point is better to use the wrapper libraries or to use the native IndexDB API in terms of cross-browsing and support and better practices?
It all depends on what you want to do with indexeddb -
If you are learning indexeddb for your interest or for knowledge then you should go for plain indexeddb. Learn and research as much you can, because it has too many apis and you will have to write code for every type of situation.
You want to use indexeddb in your project and dont have much time to explore indexeddb. You only want to do some database operations and release your project. In this case - you should go for indexedd library. This way you dont need to worry about indexeddb code . You will just write simple code using the library.
For instance : check out this article - https://dzone.com/articles/crud-operation-in-indexeddb-using-jsstore. How a library makes indexeddb so easy.
Hope this will help you.
I'm building a Google Cast integration for a music app in Chrome.
What is the difference between cast.framework.RemotePlayer and chrome.cast.media.Media?
The documentation uses cast.framework.RemotePlayer and cast.framework.RemotePlayerController, but they don't have functions for managing the queue, while chrome.cast.media.Media does.
Which one should I use?
I discovered the cast.framework namespace is used for a high-level API built on top of the chrome.cast namespace, which is a low-level API.
It doesn't matter whether you use cast.framework.RemotePlayer or chrome.cast.media.Media, both of them will work, but Media has more functions and callbacks.
In my experience, Media is easier to work with than RemotePlayer, so I don't really get why they created the RemotePlayer class.
I now need to add a feature on the app I'm building a json editor. I would like to know which module have you tried before that you think is stable and worked really well.
The source data is already in json format which I receive from an API call. I already have a button which will call $scope.viewJson() but I'm still missing which json editor module I should use. I saw this today but not sure if there is another few ones that are better - https://github.com/rodikh/angular-json-editor
I'm the author of https://github.com/rodikh/angular-json-editor.
It's basically a directive wrapper for jdorn's json-editor. His project is very popular and in active development. Both it, and my wrapper are safe to use.
If you have any feature requests or issues with my wrapper, feel free to submit an issue on github and I'll try my best to resolve them.
The best one (to my mind, but anyone is free to disagree my opinion) is formly
formly site
formly github
formly documentation
PROS :
complete (you can make beautiful and unique forms : templates are some kind like unlimited)
well documented
easy to implement
CONS :
you have to design your own builder (it is not a problem to my mind)
i know this question is old.. but i was looking for this for quite for some time.
and i found this editor 's tutorial: Ace builds
Ace builds tutorial
i found maximum above editor unmaintained.
you can check its github repo here

i hope it saves someone's time.
I'm planning to integrate RPC via JSON-RPC in my Flex applications. I've searched around the net and already found librarys for calling remote methods, but I also need to offer methods myself. None of the libs I found seemed to have this functionality.
Are there any ActionScript librarys out there which let met offer methods via JSON-RPC?
Kind regards,
Markus
If you are using playerGlobal version 10 or above than it is automatically incuded and you can directly call JSON.encode or JSON.decode methods. for PlayerGlobal version below 10, you can look for AS3CoreLib.
