Dart pub
This package is a community effort to bring support for Polymer 2 and latest HTML standards to Dart (DDC).
It features :

polymer 2.0.0 (web components 1.0)ES6 output codeimd (require js implementation using html imports)bowerPolymerize works on every platforms where DDC runs that's MacOS and Linux for now.
The upcoming version of pub will support DDC build and polymerize will support it too thus extending the platform where you can use it.
Polymerize uses DDC and Polymer-2, this means that it will only work on modern browsers. So far only chrome and firefox have been tested but Safari should work too along with latest IE11 builds.
Eventually some "transpiling" support can be added along with some optimizing post processing (like vulcanize or similar) could be added to the build chain to broaden the compatibility range.
** UPDATE ** : after moving to ** PUB+DDC ** there's something broken with firefox , will fix soon. But I wanted to publish this release quickly after 1.24 was officially released.
In order to build a project with polymerize you have to add the following transformer and dev dependencies to your pubspec:
dev_dependencies:
- polymerize: ^0.9.0
transformers:
- polymerize:
entry-point: web/index.dart
The entry point is the main dart file. Your html file should look as this:
<html>
<head>
<script src="bower_components/webcomponentsjs/webcomponents-loader.js"></script>
<script type="application/dart" src="index.dart"></script>
<script src="polymerize_require/start.js"></script>
</head>
...
</html>
See the demo todo project for more details.
pub build --web-compiler dartdevc (or add the necessary entries in the pubspec as well) ** DISCLAIMER ** : When using dartdevc for production build you will loose al the optimizations that dart2js normally makes to your code. This means that you will have bigger fat code even if modular and loaded only on demand.
A sample project illustrating how to build polymer-2 components using polymerize can be found here :
See the README for more information.
This is a sample component definition:
import 'package:polymer_element/polymer_element.dart';
import 'package:my_component/other_component.dart';
@PolymerRegister('my-tag',template:'my-tag.html')
abstract class MyTag extends PolymerElement {
int count = 0; // <- no need to annotate this !!!
onClickIt(Event ev,details) { // <- NO need to annotate this!!!!
count = count + 1; // <- no need to call `set` API , magical setter in action here
}
@Observe('count')
void countChanged(val) {
print("Count has changed : ${count}");
}
MyTag() { // <- Use a simple constructor for created callback !!!
print("HELLO THERE !")
}
factory MyTag.tag() => Element.tag('my-tag'); // <- If you want to create it programmatically use this
connectedCallback() {
super.connectedCallback(); // <- super MUST BE CALLED if you override this callback (needed by webcomponents v1) !!!!
}
}
The Html template is just the usual dom-module template without any JS code. The import dependencies will generate the appropriate html imports so there is no need to add them to
the template.
The index.html should preload imd, webcomponents polyfill and polymer.html (see the demo).
To import a bower component and use it in your project simply create a stub (that can created automatically, see below) for it and use the @BowerImport annotation along with @PolymerRegister with native=true, for instance:
@PolymerRegister('paper-button',native:true)
@BowerImport(ref:'PolymerElements/paper-button#2.0-preview',import:"paper-button/paper-button.html",name:'paper-button')
abstract class PaperButton extends PolymerElement implements imp0.PaperButtonBehavior {
/**
* If true, the button should be styled with a shadow.
*/
external bool get raised;
external set raised(bool value);
}
During the build phase polymerize will check any @BowerImport annotation on classes of dependencies, generate a bower.json file (using resolutions if you need to override something) and then
runs bower install.
You can also automatically generate a stub from the HTML polymer component using polymerize generate_wrapper, for instance:
pub run polymerize:polymerize generate-wrapper --component-refs comps.yaml --dest-path out -p polymer_elements --bower-needs-map Polymer.IronFormElementBehavior=package:polymer_elements/iron_form_element_behavior.dart
(You have to add polymerize as a dev dependency of your project).
The generator uses a yaml file describing the components to analyze passed through the component-refs options (see gen/comps.yam in this repo for an example).
The project polymerize_elements is an example of wrappers generated using this tool for the polymer-elements components.
After complilation everything will be found in the bazel output folder (bazel-bin), ready to be used.
Builder for build (use polymerizeBuilder() to generate a builder for polymerize)skip-generate: true to skip generation polymer_elements and html5 toobower_resolutions.yaml optional ovverride for polymerize init.packages (dart 1.20)paper_dialog.dart)polymerizeweb assets (not only index.html)amd is actually fully supported)You can install the package from the command line:
$ pub global activate polymerize
The package has the following executables:
$ polymerize
Add this to your package's pubspec.yaml file:
dependencies:
polymerize: "^0.9.8"
You can install packages from the command line:
with pub:
$ pub get
with Flutter:
$ flutter packages get
Alternatively, your editor might support pub get or flutter packages get.
Check the docs for your editor to learn more.
Now in your Dart code, you can use:
import 'package:polymerize/polymerize.dart';

The description is too short.
Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.
Package is pre-v1 release.
While there is nothing inherently wrong with versions of
0.*.*, it usually means that the author is still experimenting with the general direction API.
Maintain an example.
Create a short demo in the
example/directory to show how to use this package. Common file name patterns include:main.dart,example.dartor you could also usepolymerize.dart.
Use analysis_options.yaml.
