问题 I have searched far and wide on documentation on how to effectively set up Angular Dart 5 on Visual Studio Code but found nothing conclusive so far. Places I've searched already: Youtube StackOverflow https://webdev.dartlang.org - The documentation only talks about WebStorm. The VS Code plugin for dart doesn't provide functionality to make a new empty project. So I'm currently at a loss. How would I go about setting up an AngularDart 5 project on my VS Code IDE?

问题 I am building a web application using dart with web_ui. Everything was working fine until i added the web_ui pub, and now, when I am trying to run a build.dart file I get an error: Uncaught Error: type 'AttributeName' is not a subtype of type 'String' of 'name'.

Here's my code: myapp.dart: library my_library; import 'dart:html'; import 'package:web_ui/web_ui.dart'; part 'fancyoption.dart'; void main() { // Enable this to use Shadow DOM in the browser. /

问题 After developing an alpha version of a Dart-based web application, I'm interested in testing the Dart2js deployment potentials of my app. However, it doesn't seem there is a "clean" way of creating a JS deployment version of the app - the dart2js code outputs stuff to the out directory, but there is other Dart stuff in there too.
