Implementing Dark Mode and Dynamic Theming in React Native

In today’s applications, supporting dark mode and dynamic theming enhances user experience by adapting to user preferences and improving usability in different environments.

At MetaDesign Solutions, we’ve implemented theming solutions in various projects. In this blog, I’ll guide you through adding dark mode and dynamic theming to your React Native applications.

Understanding Dark Mode and Theming

Dark Mode: A color scheme that uses light-colored text and icons on dark backgrounds.
Dynamic Theming: Allowing users to switch between different themes, such as light, dark, or custom themes.

Benefits:

User Comfort: Reduces eye strain in low-light conditions.
Battery Efficiency: Saves power on devices with OLED screens.
Personalization: Enhances user engagement by offering customization.

Detecting System Theme Preferences

Using useColorScheme Hook

React Native provides the useColorScheme hook to detect the current color scheme.

Example:

jsx code:

				
					import { useColorScheme } from 'react-native';

const App = () => {
  const scheme = useColorScheme(); // 'light' or 'dark'

  return (
    <View style={scheme === 'dark' ? styles.darkContainer : styles.lightContainer}>
      {/* App Content */}
    </View>
  );
};

Implementing Theming with react-native-paper

Installation

bash code:

				
					npm install react-native-paper react-native-vector-icons

Setup

jsx code:

				
					import * as React from 'react';
import { Provider as PaperProvider, DarkTheme, DefaultTheme } from 'react-native-paper';
import { useColorScheme } from 'react-native';

const App = () => {
  const scheme = useColorScheme();
  const theme = scheme === 'dark' ? DarkTheme : DefaultTheme;

  return (
    <PaperProvider theme={theme}>
      {/* App Content */}
    </PaperProvider>
  );
};

export default App;

Customizing Themes

jsx code:

				
					const CustomDarkTheme = {
  ...DarkTheme,
  colors: {
    ...DarkTheme.colors,
    primary: '#bb86fc',
    accent: '#03dac6',
  },
};

Using react-navigation with Themes

Passing Theme to Navigation Container

jsx code:

				
					import { NavigationContainer } from '@react-navigation/native';

<NavigationContainer theme={theme}>
  {/* Navigators */}
</NavigationContainer>;

Customizing Navigation Styles

Navigation elements will adapt to the provided theme.
Customize styles using the colors object in the theme.

Implementing Dynamic Theming with Context

Creating a Theme Context

jsx code:

				
					import React, { createContext, useState } from 'react';

export const ThemeContext = createContext();

export const ThemeProvider = ({ children }) => {
  const [isDark, setIsDark] = useState(false);

  const toggleTheme = () => {
    setIsDark(!isDark);
  };

  const theme = isDark ? DarkTheme : DefaultTheme;

  return (
    <ThemeContext.Provider value={{ toggleTheme }}>
      <PaperProvider theme={theme}>{children}</PaperProvider>
    </ThemeContext.Provider>
  );
};

Using Theme Context in Components

jsx code:

				
					import { useContext } from 'react';
import { ThemeContext } from './ThemeContext';

const SettingsScreen = () => {
  const { toggleTheme } = useContext(ThemeContext);

  return (
    <Button onPress={toggleTheme}>Toggle Theme</Button>
  );
};

Handling Styles with StyleSheet

Define styles that adapt based on the theme.

jsx code:

				
					const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: theme.colors.background,
  },
});

Best Practices

Consistent Theming: Apply themes across all components for uniformity.
Performance Optimization: Avoid unnecessary re-renders when switching themes.
User Preferences: Allow users to override system settings if desired.
