Flutter App Lifecycle

Mahesh · November 2021

#this method will call when app open

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

#when app destroyed

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

#remaining states of the app, to achieve below you need to extend the class with WidgetsBindingObserver

@override
void didChangeAppLifecycleState(AppLifecycleState state) {
  if(state == AppLifecycleState.resumed){
    // user returned to our app
  }else if(state == AppLifecycleState.inactive){
    // app is inactive
  }else if(state == AppLifecycleState.paused){
    // user is about quit our app temporally
  }
}
