The "ActionSheet" dialogs do not respect the theming preferences on Android. While the iOS Action Sheets are part of the system and get their colours from the OS preferences, they're a part of the application on Android and do not change colour even when the system is in "dark mode" since the module suggests changing the module code itself for those that want to change the styles.

Solution: The react-native-action-sheet module needs to be replaced with the more well-maintained Expo/react-native-action-sheet or a forked and edited version of the current module. The expo-maintained module exposes the same options(plus customization) and is almost completely interchangeable with the currently used module while only having to add a HOC.
