@nikosfotiadis/react-native-immersive-bars NPM

Do you like the button slider that changes from light to dark mode? That's another package: react-native-button-toggle-group

Google officially suggests apps that target Q or higher to render content under the statusbar and navbar. However, doing so previously was difficult to do and required some customization and tweaking. Not to mention the variant support for other APIs.

Well, this package enables you to easily do so across various Android APIs levels. It also mocks out usage with iOS and other platforms, so you're able to use it in cross-platform apps.

⚠ This package only supports Android 5.0 and higher ⚠
This package is meant to be used alongside the react-native-safe-area-context package in order to provide proper padding and margins in order to keep scrollviews and others from being stuck forever under the navbar.
Please refer to that package's README for more information on how to use it.

Install

npm i --save react-native-immersive-bars

yarn add react-native-immersive-bars

Usage

Usage in JavaScript

import {changeBarColors} from 'react-native-immersive-bars';

// ...

React.useEffect(() => {
    changeBarColors(isDarkMode, '#50000000', 'transparent');
    // or changeBarColors(isDarkMode);
}, [isDarkMode]);

The changeBarColors function has a single required parameter and two optional ones.

isDarkMode (Required): If the app is in dark mode or not - will apply proper styling to icons and statusbar/navbar background
translucentLightStr (Optional): When a translucent bar must be drawn (due to API restrictions), what color it should be drawn in light mode
translucentDarkStr (Optional): When a translucent bar must be drawn (due to API restrictions), what color it should be drawn in dark mode

Both translucentLightStr and translucentDarkStr accept and color that Color.parseColor is able to handle as well as the string 'transparent'.

THIS MEANS THAT THREE DIGIT HEX SHORTHAND LIKE #FFF WILL CAUSE YOUR APP TO CRASH

Adding to `onCreate` (Optional)

If you only use the JavaScript code, your app will flash the navbar once the App.tsx code finally renders. If you want to avoid a jump like that, you can edit your code in:

android > app > src > main > java > yourpackagepath > MainActivity.java

And change the code to reflect this:

import com.facebook.react.ReactActivity;
import com.rnimmersivebars.ImmersiveBars; // here

public class MainActivity extends ReactActivity {
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        boolean isDarkMode = false; // Customize this to match your app's default theme
        ImmersiveBars.changeBarColors(this, isDarkMode);  // here
        super.onCreate(savedInstanceState);
    }
    // ...other code
}
