   import { Button, Text, View } from 'react-native';

    export const EditScreenInfo = ({ path }: { path: string }) => {
      const title = 'Open up the code for this screen:';
      const description =
        'Change any of the text, save the file, and your app will automatically update.';

      return (
        <View>
