## Description This PR fixes the color scheme adaptability when using `presentation: fullScreenModal`. When changing the appearance mode between `light` and `dark` the screens reacted immediately except for the fullScreenModal presentation style. When using a `UIModalPresentationFullScreen` the views belonging to the presenting view controller are removed after the presentation completes. After investigating the view hierarchy for a screen with `presentation: fullScreenModal` it turned out that the `RCTRootView` is removed, thus the `traitCollectionDidChange` observer ([see here](https://github.com/facebook/react-native/blob/d3e0430deac573fd44792e6005d5de20e9ad2797/packages/react-native/React/Base/RCTRootView.m#L362)) is not working anymore. The solution was to add an extra observer for `RNSScreenStackPresentationFullScreenModal` to be able to send proper notifications when no RCTRootView is present. As the observer is working synchronously it's usage is limited for this presentation style only. Fixes #2002. ## Changes - added repro `Test2002.tsx` - added `traitCollectionDidChange` observer for fullScreenModal ## Screenshots / GIFs ### Before https://github.com/software-mansion/react-native-screens/assets/91994767/52fa4e92-3baa-49e2-b278-7be57c4d28b3 ### After https://github.com/software-mansion/react-native-screens/assets/91994767/74c62c45-c793-4f63-81fc-d68d4000fea6 ## Test code and steps to reproduce - added `Test2002.tsx` to test examples ## Checklist - [ ] Included code example that can be used to test this change - [ ] Updated TS types - [ ] Updated documentation: <!-- For adding new props to native-stack --> - [ ] https://github.com/software-mansion/react-native-screens/blob/main/guides/GUIDE_FOR_LIBRARY_AUTHORS.md - [ ] https://github.com/software-mansion/react-native-screens/blob/main/native-stack/README.md - [ ] https://github.com/software-mansion/react-native-screens/blob/main/src/types.tsx - [ ] https://github.com/software-mansion/react-native-screens/blob/main/src/native-stack/types.tsx - [ ] Ensured that CI passes --------- Co-authored-by: Kacper Kafara <kacperkafara@gmail.com> Co-authored-by: Kacper Kafara <kacper.kafara@swmansion.com>
