Can navigator pop gesture be disabled?

I want to disable the swipe down to dismiss gesture for a navigator scene that’s floated in from the bottom, but I can’t figure out if it’s possible.

Also, componentWillUnmount() does not fire if the view is dismissed with a gesture.

The scene configs are objects with lots of overridable properties in them. If you want to start with FloatFromBottom and disable gestures, you can do this:

configureScene={() => ({
  ...Navigator.SceneConfigs.FloatFromBottom,
  gestures: {}, // or null
})

The component should unmount when dismissing with a pop gesture. That might be a bug

@ericvicenti awesome, that works!

So how about disabling only for a select few and not all screens? It seems like gestures would then need to be opt-in?

configureScene={(route) => ({
  ...route.sceneConfig || Navigator.SceneConfigs.FloatFromBottom,
  gestures: route.gestures
})}

And then when pushing a route:

// enable back gestures
this.props.navigator.push({
  title: 'Search',
  component: SearchList,
  sceneConfig: Navigator.SceneConfigs.FloatFromBottom,
  gestures: Navigator.SceneConfigs.FloatFromBottom.gestures
})

or …

// disable back gestures
this.props.navigator.push({
  title: 'Search',
  component: SearchList,
  sceneConfig: Navigator.SceneConfigs.FloatFromBottom,
  gestures: null // or just don't include this
})
