title: Navigator - SceneConfig Is It Possible To Have 'No' Transition?
body: <p>Being able to use animated transitions is awesome in Navigator. But I want to be able to flip between routes without animation and just have it quickly pop there like you would with a Tab Bar. Like 1 frame it's route A and in the next frame it's route B.</p>
  
  <p>Navigator.SceneConfigs.FadeAndroid comes close, but if I just simply accelerate the animation it has this undesirable flicker effect.</p>
  
  <p>What would a non-animated SceneConfig look like?</p>
  
  <p>Any ideas? Thanks!</p>
