Ionic serve Landscape mode


I’ve start developing a app with Ionic (ionic start name blank), and in development I’m using the ionic serve --lab.

Everything is working fine, I already have done others app with Ionic before, but the problem is, this app need to work in landscape mode, and it need to remain in that orientation. And I can’t do that.

I already changed the config.xml and added a new preference:
<preference name="orientation" value="landscape"/>

And also I tried to use this Cordova plugin:

With no luck again. Everytime I start the serve function the app is served in portrait mode. There’s a way I can develop my app (and serve it) in landscape mode?
