+```js
+// patch StatusBar.setBarStyle to make style accessible
+const _setBarStyle = StatusBar.setBarStyle;
+StatusBar.setBarStyle = (style) => {

+	_setBarStyle(style);
+};
+```
+
+You can than restore the old bar style after the browser has been dismissed like this: 
+
+```javascript
+  async openInBrowser(url) {
+    try {
+      const oldStyle = StatusBar.currentStyle
+      StatusBar.setBarStyle('dark-content')
+      await InAppBrowser.open(url)
+      if(oldStyle) StatusBar.setBarStyle(oldStyle)
+    } catch (error) {
+      Alert.alert(error.message);
+    }
+  })
+```
