Using Google Maps lib with Polymer

Asked By: Anonymous

I’m converting a Dart app that uses the GMap lib to Polymer. The map however does not seem to get rendered and nothing else of my app is as well. All I get is a blank screen. I’m not getting a runtime error.

The div where the map is rendered in is in a polymer element. In the Dart file, I’m instantiating the map like this:

final mapOptions = new MapOptions()
  ..zoom = 15
  ..center = LAT_LONG_KORTRIJK
  ..mapTypeId = MapTypeId.ROADMAP;
Element mapView = getShadowRoot("my-element").query("#mapView");
_map = js.retain(new GMap(mapView, mapOptions));

Any ideas on what be going on?

The js package does not support Shadow DOM for now. You are facing to issue-99. Until a native Element support in dart:js lands I don’t think this issue will be fixed.

Danger Zone : There could perhaps be a dirty way to work around this problem based on this message by manually replacing /packages/js/ with the content of the pointed js branch.
