Set up and debug the launch screen / splash in a React Native app using react-native-bootsplash, including light and dark variants without the paid license key. Use when the user asks about the splash screen, launch screen, bootsplash, app startup flash, a logo that is wrong or stale on launch, or a splash that stays light in dark mode; when regenerating splash assets; or before touching BootSplash.storyboard, values-night/, drawable-night-*/, or the bootsplash asset catalogs.
