This is the component (a basic page header)

import {Platform, StyleSheet, View, Text} from "react-native";
import {createRestyleComponent, createVariant} from "@shopify/restyle";
import {BoxRestyle} from "./theme";

const WebHeaderContainer = createRestyleComponent(
  [
    createVariant({
      themeKey: 'pageHeadVariants',
      defaults: {
      },
    }),
  ],
    BoxRestyle,
);

export default function WebHeader() {
    if (Platform.OS !== 'web') return null;
    return <WebHeaderContainer id='web-header'>
        <Text>Restyle Web Header</Text>
    </WebHeaderContainer>
}

// ----- theme

import {createTheme} from '@shopify/restyle';

const theme = createTheme({

  },
  textVariants: {
    header: {
      fontFamily: 'PoppinsExtraBold',
      fontWeight: '800',
      fontSize: 34,
    },
    body: {
      fontFamily: 'Roboto',
      fontWeight: '400',
      fontSize: 16,
      lineHeight: 24,
    },
    defaults: {
      // We can define a default text variant here.
    },
  },
});

export default theme;

apparently the property 'display' is causing a compile error. Why? shouldnt I be able to say display: 'flex'?
