dart - What is the difference between @observable and @published -

until polymer 0.10.1 @published annotation created attribute on polymer element declared.
changed polymer 0.11.0. since @publishedproperty(reflect: true) needed make fields value available attribute.

it seems since update @published has same effect @observable. missing something?

the @published attribute still allows use value attribute in html declaratively. can still do:

<my-element myprop="{{hello}}"></my-element> 

the change accessing values procedurally via attributes property, must include @publishedproperty(reflect: true). (this not seem case if you're interactive customtag class directly.

needs @publishedproperty(reflect: true):

var x = queryselector('x-foo'); x.bar = "hi"; // ... print(x.attributes["bar"]); 

this needs @publishedproperty(reflect: true):

/* css */ x-foo[bar="hi"] { background-color: blue; } 

this not:

xfoo x = queryselector('x-foo'); x.bar = "hi"; ... print(x.bar);
