Quick Start

import { ThemeProvider, useThemedStyles, useTheme } from "rn-theme-wrapper";

Provide default color theme to ThemeProvider

const App = () => {
  const defaultColors = {
    id: 1,
    BACKGROUND: "#ecf0f1",
    BACKGROUND_SECONDARY: "#ffffff",
    TEXT: "#171717",
    TEXT_SECONDARY: "#686D76",
    PRIMARY: "#FF5714",
    SECONDRY: "#6EEB83",
  };

  const typography = {
    size: {
      S: 16,
      M: 20,
      L: 30,
    },
    letterSpacing: {
      S: 2,
      M: 5,
      L: 10,
    },
  };

  return (
    <ThemeProvider defaultTheme={{ colors: defaultColors, typography }}>
      <YOUR_NAVIGATION_STACK />
    </ThemeProvider>
  );
};

Use theme into stylesheet

import { View, StyleSheet, Image, Text } from "react-native";
import { useThemedStyles, useTheme } from "rn-theme-wrapper";

export const Item = ({ data, loading }) => {
  const style = useThemedStyles(styles);
  const theme = useTheme();
  return (
    <View style={style.mainBox}>
      <Text>Applyed theme</Text>
    </View>
  );
};

const styles = (theme) =>
  StyleSheet.create({
    mainBox: {
      height: 130,
      width: 130,
      borderRadius: 12,
      justifyContent: "center",
      alignItems: "center",
      backgroundColor: theme.colors.PRIMARY,
      marginRight: 22,
      shadowColor: "#000",
      shadowOffset: { width: 1, height: 1 },
      shadowOpacity: 0.4,
      shadowRadius: 3,
      elevation: 5,
      marginBottom: 8,
    },
  });

Change theme

const darkTheme = {
  id: 2,
  BACKGROUND: "#2c2b2e",
  BACKGROUND_SECONDARY: "#141414",
  TEXT: "#ecf0f1",
  TEXT_SECONDARY: "#bdc3c7",
  PRIMARY: "#FF5714",
  SECONDRY: "#6EEB83",
};

const theme = useTheme();

//This function will change a theme in the theme provider
theme.customeTheme(darkTheme);

FAQ

Q: Why should I need to use this? A: Because this theme wrapper can directly serve the theme to the app style sheet another library is not providing these facilities so as a developer it will reduce development time for theme management functionality.

Q: How does the package lightweight and provides high performance? A: We are only providing the required functionality which is a basic need of all apps so we avoid unwanted theme features that's why the package is lightweight. And package logic and function are dependent on javascript and ES6 modules so this package will not link to the native platform and this will provide high performance.

Q: How it will help to improve code quality? A: Yes this library will help you to maintain code quality because the whole app theme will be managed in a single config file and we will not provide any hardcoded color to any component so the coding standard and code quality will improve.

Support

This library will support all es6 supported react-native versions and functional components.
