📝 Get Started

StyleSheet

Is similar to the usual styling format, but now you have additional props to make style themeable.

T() - Themed Function

Apply only your themed styles using the T() function wrapper.

TV() - Themed Value Function

Is an extra helper function that can be used to theme a specific value. (it becomes useful with react navigation)

appearanceHook

Use the appearanceHook to switch theme from anywhere in your app.

🌓 Expo: To make the system preference work, make sure "userInterfaceStyle":"automatic" is added to app.json

Usage ❓

// Styles
import { StyleSheet, T, appearanceHook } from 'theme-csx';

// Components
import { Text, View } from 'react-native';
import { Button } from '@components/atoms';

const DemoComponent = () => {
  // Theme switch
  const switchTheme = () => {
    switch (appearanceHook.activeTheme) {
      case 'dark':
        appearanceHook.switch('light');
        break;
      case 'light':
        appearanceHook.switch('system');
        break;
      default:
        appearanceHook.switch('dark');
        break;
    }
  };

  return (
    <View style={T(styles.THEMED_CONTAINER)}>
      <Text style={styles.NORMAL_TEXT}>Hey, I am normal text</Text>

      <Text style={T(styles.THEMED_TEXT)}>Hey, I am themed text</Text>

      <Button text={'Switch theme'} onPress={switchTheme} />
    </View>
  );
};

const styles = StyleSheet.create({
  THEMED_CONTAINER: {
    flex: 1,
