Trigger FirstPage's setState method after popping Second page

I have two pages in myapp namely FirstPage and SecondPage.

Basically, FirstPage widget displays a ListView with a list of items while SecondPage widget is where I can add/delete items to the list.

I can navigate to the SecondPage by:

Navigator.of(context).pushNamed("/SecondPage");

And also I can go back to the FirstPage by using:

Navigator.of(context).pop();

My problem is I can't figure out how am I going to trigger the setState method of FirstPage widget after popping the SecondPage so that the FirstPage's ListView is updated.

I would appreciate any hint.


Whenever we push, we will get a future, we can use that future to trigger the setState

Future pushNamed = Navigator.of(context).pushNamed("/SecondPage");
pushNamed.then((_)=> setState(() {}));

Refer here to send data from secondScreen to firstScreen.

(not app.module.ts). add this to same  Identifying Triggers Write “Triggers” on the second tab and insert several sheets of paper. On the first page, write down those things that, if they occur, might cause an increase in your symptoms. They may have triggered or increased symptoms in the past.


Use this code to send values from child View to your parent view

 Widget build(BuildContext context) {
return new Scaffold(
  appBar: new AppBar(
    title: new Text(widget.title),
  ),
  body: new Center(
      child: new FlatButton(
          onPressed: () {
            Navigator.push(
              context,
              MaterialPageRoute(
                  builder: (context) => SecondView(callBackValue)),
            );
          },
          child: new Text('Open Child Widget'))),
);
}

 //Your Callback Values will be received here
void callBackValue(double value) {
print('Value $value');
}

// Your SecondPage
class SecondView extends StatefulWidget{
    final void Function(double data) callback;
    SecondView(this.callback);

    @override
    _SecondView createState() => new _SecondView();
  }

  class _SecondView extends State<SecondView>{
    @override
    Widget build(BuildContext context) {
      return new Scaffold(
        appBar: new AppBar(
          title: new Text('Child Widget'),
        ),
        body: new Center(
          child: new FlatButton(onPressed: (){
            widget.callback(10.0);
          }, child: new Text('Send Value to parent')),
        ),
      );
    }
  }

what you trying to achieve is similar to the startActivityForResult() method in Android.

This can be achieved in flutter something like this :-

in your first activity

  Map map = await Navigator.of(context).push(MaterialPageRoute(builder: (context) => SecondView());

// now it will wait for the secondView to return some data
//and the below code will be executed whenever the second view pops.
  setState((){});

Hope this was helpful.

And dont forget to write async in your method declaration for the navigation.

  void _navigateToSecondActivity async {
       Map map = await Navigator.of(context).push(MaterialPageRoute(builder: (context) => SecondView());
       setState((){});
  }

Just call this function when you need to navigate to the second activity.

or on your onTap()

onTap: () async{
  Map map = await Navigator.of(context).push(MaterialPageRoute(builder: (context) => SecondView());
       setState((){});
}

Tracking Single Page Applications with Google Analytics, Only the first page is tracked; Page paths do not include fragment data Analytics Tag and a Trigger that fires on the custom event 'pageview':  Im using material paginator for paging some custom cards. And i made a selector for filter the data. I want to trigger paginator go to first page event when i changed the selector value. Because for example while im looking at page 10 and changed filter value paginator show me the empty page if i dont have enough data to show at 10.page.
