Force Flutter navigator to reload state when popping

Question

I have one StatefulWidget in Flutter with button, which navigates me to another StatefulWidget using Navigator.push(). On second widge

Answer 1

This work really good, i got from this doc from flutter page: flutter doc

I defined the method to control navigation from first page.

_navigateAndDisplaySelection(BuildContext context) async {
    final result = await Navigator.push(
      context,
      MaterialPageRoute(builder: (context) => AddDirectionPage()),
    );

    //below you can get your result and update the view with setState
    //changing the value if you want, i just wanted know if i have to  
    //update, and if is true, reload state

    if (result) {
      setState(() {});
    }
  }

So, i call it in a action method from a inkwell, but can be called also from a button:

onTap: () {
   _navigateAndDisplaySelection(context);
},

And finally in the second page, to return something (i returned a bool, you can return whatever you want):

onTap: () {
  Navigator.pop(context, true);
}
