angularjs - Is there something similar to angular $rootScope in Polymer.dart? -


i know in angular exists called $rootscope. 1 contains variables going shared controllers. i'm looking similar polymer, don't need pass parent variable attributes always.

right i'm doing similar this:

index html code:

<body>   <my-parent-component some-attribute="hello"></my-parent-component> </body>

parent html code:

<my-parent-component>   <template>     <p>someattribuet used parent: {{someattribute}}</p>     <my-child-component some-attribute="{{someattribute}}"></my-child>   </template> </my-parent-component>

parent dart code:

class myparentcomponent extends polymerelement {   @published var someattribute; }

child html code:

<my-child-component>   <template>     <p>some attribute used here: {{someattribute}}</p>   </template> </my-child-component>

child dart code:

class mychildcomponent extends polymerelement {   @published var someattribute; }

in other words, i'm passing attribute way down top parent until lowest child. think not , similar $rootscope in angular.

polymer doesn't have root scope. in polymer there element , maybe parent elements or child elements can reference in expression. more generic solution global variables or globals element explained here https://stackoverflow.com/a/29864797/217408
