Is there any lib compatible with dart:js for flutter ?

[Diego Garcia]

Hi guys, I`m trying to use this signalr lib https://github.com/Layoric/SignalDart/blob/master/lib/signal_dart.dart on my flutter app, but its missing the dart:js and I cant find a way to import it,  I`ve looked for some equivalent on flutter but couldnt find ...

Any tips on how to fix it?

I'm getting the follow error when compiling: 

keep receiving the follow error compiler message: dart:js: Error: Not found: dart:js.

Best Regards,

The dart:js library is available when you're running Dart in a web browser.  It's what lets your Dart code interact with other JavaScript code running in the web page.  In Flutter's case, there isn't any JavaScript code around because Flutter isn't based on WebView.

It looks like that library is mostly providing a bridge to a JavaScript implementation of SignalR.  You'd probably need a Dart-based implementation for it to work in Flutter because Flutter doesn't have a JavaScript VM.

Thanks Adam, I didnt noted that it was bridging the original implementation only.  

Will look for the signalr documentation and the javascript file to see how to port to dart code only.

That library is a bit old, and I wouldn't be surprised if it doesn't pass Dart 2's strong mode. You'll probably be better off forking it and making whatever changes necessary.

Yap, I've tried that other one https://pub.dartlang.org/packages/signalr2#-readme-tab- but it has the same dependency on dart:js

Will look on fork it and implement the client part on dart, maybe using websockets.
