BackHandler is not working in react-native side-menu when using react-native router-flux
I am working on react-native to develop a sample application. Here I got an issue when I was using backHandler in the react-native side-menu component.
Actually, the side menu contains more pages! But when clicking the Android back button in the side menu pages, only once the back handler works. Here I am using react-native router-flux.
Here the back button action is called only once!
This is my code:
componentDidMount()
BackHandler.addEventListener('hardwareBackPress', this.handleBackPress);
componentWillUnmount()
BackHandler.removeEventListener('hardwareBackPress', this.handleBackPress);
handleBackPress = () =>
let isGoback = this.props.isGoback
//alert("Hi " + isGoback)
if(isGoback === "Contact Us")
//alert("Hi: " + isGoback)
Actions.BasicSideMenuMain(selectedItem:'Home');
//Actions.replace('BasicSideMenuMain')

What do you mean by "once the back handler function calls here main screen is Home"? Can you fix it (by editing your question, not by responding here in comments)?

I had the same issue this is how I solved it:
As you are using router-flux you can use Actions.currentScene to find which page you are on
handleBackPress = () =>
if(Actions.currentScene === 'mainPage') // 'mainPage' is kay of your scene
BackHandler.exitApp(); // or anything you want
return false;
Actions.pop(); // for all the pages beside mainPage in side menu always go back
return true;
Hope it works.
