In the ever-evolving world of mobile app development, creating visually stunning and immersive user experiences is paramount. Enter react-native-edge-to-edge, a powerful library that allows React Native developers to effortlessly enable edge-to-edge display on Android devices. This innovative approach lets your app content flow seamlessly beneath the system bars, maximizing screen real estate and providing a more engaging user interface.

Embracing the Edge: Key Features

react-native-edge-to-edge brings a host of features to the table, making it an essential tool for React Native developers targeting Android platforms:

  1. Effortless Edge-to-Edge Display: Enable full-screen content with minimal configuration.
  2. System Bar Management: Easily control the appearance and behavior of status and navigation bars.
  3. Future-Proof Development: Prepare your apps for upcoming Android requirements, particularly Android 15’s edge-to-edge enforcement.
  4. Cross-Platform Consistency: Achieve a unified look across iOS and Android platforms.
  5. Immersive Mode Support: Create captivating full-screen experiences without deprecated APIs.

Getting Started: Installation and Setup

Let’s dive into how you can integrate react-native-edge-to-edge into your project.

Installing the Package

To begin, install the package using your preferred package manager:

npm install react-native-edge-to-edge
# or
yarn add react-native-edge-to-edge

Configuration for Different Environments

For Expo Users

If you’re using Expo, add the library plugin to your app.json configuration file:

{
  "expo": {
    "plugins": ["react-native-edge-to-edge"]
  }
}

Remember to create a new build after making this change.

For Bare React Native Projects

For those using bare React Native, modify your android/app/src/main/res/values/styles.xml file:

<resources>
  <style name="AppTheme" parent="Theme.EdgeToEdge">
    <!-- Your existing style properties -->
  </style>
</resources>

This change ensures your app inherits the necessary theme for edge-to-edge display.

Harnessing the Power: Basic Usage

Now that we’ve set up react-native-edge-to-edge, let’s explore how to use its core component: SystemBars.

Implementing SystemBars

The SystemBars component is your gateway to managing system bars in your app. Here’s a basic implementation:

import React from 'react';
import { View, Text } from 'react-native';
import { SystemBars } from 'react-native-edge-to-edge';

const App = () => {
  return (
    <View style={{ flex: 1 }}>
      <SystemBars style="light" />
      <Text>Welcome to my edge-to-edge app!</Text>
    </View>
  );
};

export default App;

In this example, we’ve added the SystemBars component at the root of our app, setting the system bar style to “light”. This ensures that the status bar content will be light-colored, suitable for dark backgrounds.

Customizing SystemBars Appearance

The SystemBars component accepts various props to customize its behavior:

type SystemBarsProps = {
  style?: "auto" | "light" | "dark";
  hidden?: boolean | { statusBar?: boolean; navigationBar?: boolean };
};

Let’s see how we can use these props:

import React from 'react';
import { View, Text } from 'react-native';
import { SystemBars } from 'react-native-edge-to-edge';

const App = () => {
  return (
    <View style={{ flex: 1, backgroundColor: 'black' }}>
      <SystemBars
        style="light"
        hidden={{ statusBar: true, navigationBar: false }}
      />
      <Text style={{ color: 'white' }}>Immersive edge-to-edge experience!</Text>
    </View>
  );
};

export default App;

In this example, we’ve set the system bars to light style and hidden the status bar while keeping the navigation bar visible. This creates an immersive experience where your app’s content can utilize the full screen, with only the navigation bar remaining visible.

Advanced Techniques: Mastering SystemBars

For more complex scenarios, react-native-edge-to-edge offers advanced methods to manage system bars dynamically.

Dynamic System Bar Management

Sometimes, you might need to change the system bar configuration based on different app states or user interactions. The library provides methods to handle this:

import { SystemBars } from 'react-native-edge-to-edge';

// Push a new configuration onto the stack
const entry = SystemBars.pushStackEntry({ style: 'dark', hidden: false });

// Later, when you want to revert to the previous state
SystemBars.popStackEntry(entry);

// Or, if you want to replace the current configuration
const newEntry = SystemBars.replaceStackEntry(entry, { style: 'light', hidden: true });

These methods allow you to manage system bar configurations in a stack-like manner, perfect for handling different screens or modals in your app.

Handling Different Screen Orientations

When dealing with orientation changes, you might want to adjust your system bar configuration accordingly:

import React, { useState, useEffect } from 'react';
import { View, Dimensions } from 'react-native';
import { SystemBars } from 'react-native-edge-to-edge';

const OrientationAwareApp = () => {
  const [isLandscape, setIsLandscape] = useState(false);

  useEffect(() => {
    const updateOrientation = () => {
      const { width, height } = Dimensions.get('window');
      setIsLandscape(width > height);
    };

    Dimensions.addEventListener('change', updateOrientation);
    return () => Dimensions.removeEventListener('change', updateOrientation);
  }, []);

  return (
    <View style={{ flex: 1 }}>
      <SystemBars
        style={isLandscape ? 'light' : 'dark'}
        hidden={isLandscape}
      />
      {/* Your app content */}
    </View>
  );
};

export default OrientationAwareApp;

This example demonstrates how to adjust the system bar configuration based on the device’s orientation, providing a tailored experience for both portrait and landscape modes.
