I got a problem while deploying Dart code using Polymer to Javascript. I've created a polymer application with DartEditor and made a simple example. This example works in Dartium but when I try to build it as a Polymer App (in Javascript) and launch it, the app fails.
How am I supposed to convert a Dart Polymer app to Javascript ?
Here's the example code I made that fails :
example.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Example</title>
<link rel="import" href="example-polymer.html">
<script type="application/dart">export 'package:polymer/init.dart';</script>
<script src="packages/browser/dart.js"></script>
</head>
<body>
<div is="example-polymer"></div>
</body>
</html>
example-polymer.html
<polymer-element name="example-polymer" extends="div">
<template>
<div>
<input on-change="{{ change }}"/><br>
<span>Text : {{ text }}</span>
</div>
</template>
<script type="application/dart" src="example-polymer.dart"></script>
</polymer-element>
example-polymer.dart
import 'package:polymer/polymer.dart';
import 'dart:html';
@CustomTag('example-polymer')
class ExampleBolymer extends DivElement with Polymer, Observable {
@published String text = "" ;
ExampleBolymer.created() : super.created() {
}
void change(Event e, var detail , InputElement target) {
text = target.value;
}
}
add
to your pubspec.yaml and call
Your files should be in the
webdirectory of your package.
