 Version 6 also includes a new set of [wrappers](./components/src/themed) around a subset of [React Native Paper](https://callstack.github.io/react-native-paper/index.html) components to provide the correct styles. In order to get the correct appearance, you should use these themed wrapper components instead of the components directly from RNP. These wrapper components should be used in conjunction with version 6+ of [@brightlayer-ui/react-native-themes](https://www.npmjs.com/package/@brightlayer-ui/react-native-themes), which consolidated our blueDark and blueDarkAlt themes into a single theme for simpler usage.
