• ✅ Hex-based status bar background color control
• ✅ Current color getter for runtime queries
• ✅ Simple React hook and SafeArea wrapper component
• ✅ 100% compatible with Expo EAS Build and bare React Native
• ✅ Full TypeScript support (auto-complete and type definitions)

📦 Installation

Using npm

npm install rns-statusbar

Using yarn

yarn add rns-statusbar

⚙️ Expo / EAS Setup

If you use Expo Prebuild / EAS Build, the plugin is automatically registered in your configuration.
You can confirm that your app.json or app.config.js includes:

{
  "expo": {
    "plugins": ["rns-statusbar"]
  }
}

Then rebuild your native project:

npx expo prebuild

For local production builds:

eas build --platform android --local

🧱 Bare React Native Setup

If using plain React Native (without Expo):

iOS Setup

• Install the package
• Navigate to iOS directory and install pods

  cd ios && pod install
  

• Rebuild your project.

Android Setup

• Install the package
• Sync Gradle and rebuild your project.

🧩 Usage Example

import React, { useEffect } from 'react';
import {
  SafeArea,
  getStatusBarHeight,
  getStatusBarColor,
  setStatusBarColor,
  useTopPadding,
} from 'rns-statusbar';

export default function App() {
  const topPadding = useTopPadding();

  useEffect(() => {
    setStatusBarColor('#20232a');     // Set background color
    getStatusBarHeight().then(console.log); // Log status bar height
    getStatusBarColor().then(console.log);  // Log current color
  }, []);

  return (
    <SafeArea style={{ backgroundColor: '#fff' }}>
      <Text style={{ marginTop: topPadding }}>Hello Status Bar!</Text>
    </SafeArea>
  );
}

🔧 API Reference

Functions

Function	Type	Description

</SafeArea>

children	React.ReactNode	Nested content.

🧾 TypeScript Support
