How are you trying to enter immersive mode?

[chelarustefan]

i am using this package https://www.npmjs.com/package/react-native-immersive

Are you using drawBehind: true property on the topBar when you enter immersive mode?

[chelarustefan]

yes it's set to true also the orientation it is set to landscape

I'm actually experimenting with this now in windowInsets branch.

It includes a new options to modify the navigationBar

navigationBar: {
  drawBehind: true | false,
  backgroundColor: String
}

The downside of this branch is that it in order to handle drawing under the status bar and the navigation bar - I had to handle all insets myself rendering android:windowSoftInputMode="adjustResize" useless. This means the system doesn't handle insets for you when the keyboard opens for example and instead RNN handles all insets.
I'm a bit hesitant to introduce this change as I'm not entirely sure what effects it will have.

        topBar: {
          visible: false,
           height: 0,
           drawBehind: false
         },
         statusBar: {
           drawBehind: true,
           visible: true,
           style: 'dark',
           backgroundColor: 'transparent'
         }

it works!

Any plans to merge this into master (drawing behind the navigation bar?)
