I have a webview in my app. I set onNavigationStateChange props for it to handle click on any link on webview and navigate user to browser.
The issue is when the user press BackAndroid on browser on come back in my app webview content not showing and screen is empty and white.
For this issue I try to use appState and handle its changes to reload webview after coming back in my app, but got this error 
Here is my code:
function Screen(props) {
const [appState, setAppState] = React.useState(AppState.currentState);
let webview = React.useRef(null);
React.useEffect(() => {
AppState.addEventListener('change', handleAppStateChange);
return () => AppState.removeEventListener('change', handleAppStateChange);
}, []);
function backHandler() {
popScreen(Screens.About);
return true;
}
function handleAppStateChange(nextAppState) {
if (nextAppState === 'active') {
webview.reload();
}
setAppState(nextAppState);
}
const WebView = require('react-native-webview').default;
return (
<View style={styles.container}>
<View style={styles.web}>
<WebView
ref={ref => {
webview = ref;
}}
source={{uri: props.link}}
androidHardwareAccelerationDisabled={true} // for prevent crash
startInLoadingState={true}
onNavigationStateChange={event => {
if (event.url !== props.link) {
webview.stopLoading();
Linking.openURL(event.url);
}
}}
renderLoading={() => (
<CircleLoading
containerStyle={[styles.loading]}
renderLoading={true}
/>
)}
/>
</View>
</View>
);
}
Thanks.
