Expo StatusBarA library that provides the same interface as the React Native StatusBar API, but with slightly different defaults to work great in Expo environments.
GitHub
npm
expo-status-bar gives you a component and imperative interface to control the app status bar to change its text color, background color, hide it, make it translucent or opaque, and apply animations to any of these changes. Exactly what you are able to do with the StatusBar component depends on the platform you're using.
Web support
There is no API available on the web for controlling the operating system status bar, so
expo-status-barwill no-op, so it will do nothing and will not error.
Installation
-Â npx expo install expo-status-barIf you are installing this in an existing React Native app (bare workflow), start by installing expo in your project. Then, follow the additional instructions as mentioned by library's README under "Installation in bare React Native projects" section.
Usage
import { StyleSheet, Text, View } from 'react-native';
import { StatusBar } from 'expo-status-bar';
export default function App() {
return (
<View style={styles.container}>
<Text style={styles.text}>Notice that the status bar has light text!</Text>
<StatusBar style="light" />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#000',
alignItems: 'center',
justifyContent: 'center',
},
text: {
color: '#fff',
},
});
API
import { StatusBar } from 'expo-status-bar';
Component
StatusBar
Type: React.Element<StatusBarProps>
A component that allows you to configure your status bar without directly calling imperative
methods like setBarStyle.
You will likely have multiple StatusBar components mounted in the same app at the same time.
For example, if you have multiple screens in your app, you may end up using one per screen.
The props of each StatusBar component will be merged in the order that they were mounted.
This component is built on top of the StatusBar
component exported from React Native, and it provides defaults that work better for Expo users.
animated
Optional • Type: boolean
If the transition between status bar property changes should be
animated. Supported for backgroundColor, barStyle and hidden.
Optional • Type: boolean
If the status bar is hidden.
hideTransitionAnimation
Optional • Type: StatusBarAnimation • Default: 'fade'
The transition effect when showing and hiding the status bar using the hidden prop.
networkActivityIndicatorVisible
Optional • Type: boolean
If the network activity indicator should be visible.
style
Optional • Type: StatusBarStyle • Default: 'auto'
Sets the color of the status bar text. Default value is "auto" which
picks the appropriate value according to the active color scheme, eg:
if your app is dark mode, the style will be "light".
translucent
Optional • Type: boolean
If the status bar is translucent. When translucent is set to true,
the app will draw under the status bar. This is the default behaviour in
projects created with Expo tools because it is consistent with iOS.
