HtmlImport annotation. This can be added to any library declaration and it will inject an html import to the specified path into the head of the current document, which allows dart files to declare their html dependencies. Paths can be relative to the current dart file or they can be in
Note: Html imports included this way cannot contain dart script tags. The mirror based implementation injects the imports dynamically and dart script tags are not allowed to be injected in that way.
Note: Relative urls cannot be used in inlined script tags. Either move the script code to a Dart file, use a
package: url, or use a normal HTML import. See https://github.com/dart-lang/web-components/issues/6.
web_components transformer. This should be used in place of the
initialize transformer if that already exists in your application (it will call that transformer). This will inline html imports (including @HtmlImport annotations) into the head of your document at compile time, it can be used like this:
transformers: - web_components: entry_points: - web/index.html
entry_points option is supplied then any html file under
test will be treated as an entry point.
registerDartType. In order to use this you will need to be using the
initializepackage, and call its
runmethod from your main function. It is also recommended that you include the transformer from that package to remove the use of mirrors at runtime, see initialize for more information.
platform.jshas been replaced with
webcomponents.js. Also, the default file is now unminified, and the minified version is called
.concat.jsfiles during release mode.
Updated to platform version 0.4.2, internally a deprecated API was removed, hence the bump in the version number.
split dart_support.js in two. dart_support.js only contains what is necessary in order to use platform.js, interop_support.js/interop_support.html can be imported separately when providing Dart APIs for js custom elements.
node. There is no longer a single global observer, but one for each ShadowRoot and one for the main document. The observer that is actually used defaults to the main document, but if
nodeis supplied then it will walk up the document tree and use the first observer that it finds.
