[RamkumarBPE]

Version

Tell us which versions you are using:Router Flux -

• react-native-router-flux v4.?.? 4.0.0-beta.24
• react-native v0.?.? 0.53.0

Expected behaviour

I just want to disable the transition animation.
Ex: when I navigate to a screen "Actions.sceneName()", there is a sliding transition animation from left to right. I just want to disable the sliding transition.

Actual behaviour

Transition happens like sliding Door, when navigating between scenes.I tried using direction=vertical. It works in Android, but in iOS it is not working.

1. Open app
