? React Native StatusBar

? Quick Overview

The StatusBar component in React Native allows you to control the appearance of the device’s status bar such as background color, text color, visibility, and transparency. It helps create immersive and platform-consistent mobile UI experiences.

? Key Concepts

• Controls system-level UI at the top of the screen
• Supports light and dark content styles
• Works differently on Android and iOS
• Can be configured globally or per screen

? Syntax / Theory

The StatusBar component is imported from react-native and used inside your component tree. On Android, you can change background color and translucency, while on iOS you mainly control text style and visibility.

// Import StatusBar from react-native
import { StatusBar } from "react-native";

// Basic StatusBar usage
<StatusBar barStyle="dark-content" />

? Code Example(s)

// Full example demonstrating StatusBar customization
import React from "react";
import { View, Text, StatusBar } from "react-native";

export default function App() {
  return (
    <View style={{{ flex: 1, backgroundColor: "#2563eb", justifyContent: "center", alignItems: "center" }}}>
      <StatusBar backgroundColor="#2563eb" barStyle="light-content" />
      <Text style={{{ color: "white", fontSize: 18 }}}>StatusBar Example</Text>
    </View>
  );
}
