Defining a global filter/transformer in Polymer.dart
I'm not aware of a global way to define a transformer, but I use the following workaround:I have a class containing my global transformers, that are included into my custom elements using a mixin. Put it into a library that you include into every element. My global transformer mixin:
abstract class GlobalTransformersMixin extends Object implements Observable { @observable final Transformer asInteger = new _StringToInt(); //...}Using it in an custom element:
@CustomTag('my-elment')class MyElement extends PolymerElement with GlobalTransformersMixin { //...}
