Introduction

React Native Safe Area Context is a library that provides a way to handle safe areas in React Native applications. The library react-native-safe-area-context is typically used with React Navigation or other navigation libraries to ensure that your app's content is positioned correctly and visible within the safe area on various devices. It lets you define and handle safe area insets to ensure system elements do not obscure your UI components.

What is a Safe Area?

Recently, smartphone companies have manufactured smartphones with unique designs to make customer interaction more worthwhile. This sometimes results in smartphones having system elements or hardware features like notches, camera cutouts, or curved screens, which reduce the available screen space. 

Safe Area

The safe area ensures that UI elements and content are positioned within the visible and usable portion of the screen. this helps prevent important information or interactive features from being hidden or obscured by the device's hardware components, such as the status bar, navigation bar, or rounded corners.

The specific dimensions of the safe area vary depending on the device and its screen design. For example, on an iPhone X or newer models, the safe area excludes the rounded corners, notch area, and home indicator. On Android devices, the safe area may also vary based on the device manufacturer and software version.

React-native-safe-area-context

React Native Safe Area Context is a tool provided to us to display our app's content correctly on different mobile devices, especially those with notches or curved screens. It ensures that the functionality of our app is not hidden or cut off by things like the device's status bar, rounded corners, or navigation bar and provides a better user experience.

Think of it like this When you look at your phone, you'll notice that some areas on the screen are always visible, and some may be hidden because of the phone's shape or special features. As we already know, The parts that are always visible, and don't get blocked or covered up, are called the "safe area."

Now, when we build mobile apps using React Native, we want to make sure our app's content is displayed correctly within that safe area on different devices. That's where React Native Safe Area Context comes in.

With React Native Safe Area Context, we use a particular library that helps us handle the safe area in our app. It works with other navigation libraries to ensure our app's content is positioned correctly and not hidden by the device's hardware.

By using React Native Safe Area Context, we can ensure that our app looks good on different devices, regardless of their screen shapes or special features. It's like a helpful tool that takes care of our safe area, so we can focus on building our app without worrying about the content being hidden or cut off.

Installation 

To use react-native-safe-area-context, you need to follow these steps:


Step 1. Install the library by running the following command:

npm install react-native-safe-area-context.


Step 2. Import the necessary components in your JavaScript/TypeScript file:

import { SafeAreaProvider, SafeAreaView } from 'react-native-safe-area-context';


Step 3. Wrap your top-level component with SafeAreaProvider to make it aware of safe area insets:

const App = () => {
 return (
   <SafeAreaProvider>
     {/* Your app components */}
   </SafeAreaProvider>
 );
};


Step 4. Use the SafeAreaView component in place of the regular View component where you want to respect safe area insets:

const MyScreen = () => {
 return (
   <SafeAreaView style={{ flex: 1 }}>
     {/* Your screen content */}
   </SafeAreaView>
 );
};


Note that react-native-safe-area-context works on both iOS and Android devices, providing a consistent way to handle safe areas in your React Native apps.

React Native SafeAreaProvider 

React Native Safe Area Context provides a SafeAreaProvider component that wraps the root navigator or screen component where you want to handle safe area insets. To ensure that the SafeArea is correctly used in your application, it is recommended to include the SafeAreaProvider in the root component of your app, as shown below.

import { SafeAreaProvider } from 'react-native-safe-area-context';
function App() {
 return <SafeAreaProvider>...</SafeAreaProvider>;
}


The component accepts all the properties of the View component in React Native. By default, it has a style of {flex: 1}.

React Native SafeAreaView

The SafeAreaView is a type of View component in React Native that automatically applies safe area insets as either padding or margin. Safe Area View provides many features, including padding and margins, To adjust the spacing within the safe area. 

For example:


import { SafeAreaView } from 'react-native-safe-area-context';
function SomeComponent() {
 return (
   <SafeAreaView style={{ flex: 1, backgroundColor: 'red' }}>
     <View style={{ flex: 1, backgroundColor: 'blue' }} />
   </SafeAreaView>
 );
}

Frequently Asked Questions

Do I need to handle safe areas manually without React Native Safe Area Context?

Without using React Native Safe Area Context, you would need to handle safe areas manually by calculating and adjusting the layout based on device-specific safe area insets. React Native Safe Area Context simplifies this process by automatically providing an abstraction layer to handle safe areas.

Can I customize the styles of SafeAreaView?

Yes, you can style the SafeAreaView component just like a regular View. Apply styles such as flex, padding, background color, etc., to achieve the desired layout and appearance within the safe area.

Does React Native Safe Area Context work on both iOS and Android?

Yes, React Native Safe Area Context works on both iOS and Android devices. It provides a consistent way to handle safe areas and adapt the UI based on the device's safe area insets.

Can I use React Native Safe Area Context with navigation libraries?

Yes, React Native Safe Area Context is often used in combination with navigation libraries like React Navigation. It helps ensure that the content within navigation screens is appropriately positioned and visible within the safe area.
