Flutter: Navigator.pop(context);

Question

I pass a page with this code below.

Navigator.push(context,
  MaterialPageRoute(builder: (context) => FileFolder()));

for example, I change some data in FileFolder(); page. And I want to get this data to my first page what I change data. I use Navigator.pop(context); but this code is not run initstate((){});. How can I refresh my first page?

Answer 1

You can write your code inside initstate((){}); method like below:

    Future.delayed(Duration.zero, () {
     Navigator.push(context,
     MaterialPageRoute(builder: (context) => FileFolder()));
    });

Answer 2

//first page
    Future data = await Navigator.push(context,
        MaterialPageRoute(builder: (context) => FileFolder()));

    setState(() {
      myData = data;
    });

//second page FileFolder
    Map data = {};
    Navigator.pop(context,data);
