you can use this as an example:

class AppLifecycleReactor extends StatefulWidget
{
  @override
  _AppLifecycleReactorState createState() => _AppLifecycleReactorState();
}

class _AppLifecycleReactorState extends State with WidgetsBindingObserver {

  @override
  void initState(){
    super.initState();
    WidgetsBinding.instance!.addObserver(this);
  }

  @override
  void dispose(){
    super.dispose();
    WidgetsBinding.instance!.removeObserver(this);
  }

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    super.didChangeAppLifecycleState(state);
    print("App Lifecycle State : $state");
  }

  @override
  Widget build(BuildContext context) {

  }
