Opening same route from drawer of the same activity result in black screen #16601

Steps to Reproduce

I am trying to write an application which has the same navigation drawer in all the activities including the one's present in the navigation drawer. Whenever I try to open an activity from the navigation drawer of the same activity, I get the error

main.dart code

final GlobalKey<ScaffoldState> _scaffoldState = new GlobalKey<ScaffoldState>();

void main() => runApp(new MaterialApp(
  home: new StudentList(),
  routes: <String, WidgetBuilder>{
    'parentProfile' : (BuildContext context) => new ParentProfile(),
  },
  debugShowCheckedModeBanner: false,
));

student_list.dart code

final GlobalKey<ScaffoldState> _scaffoldState = new GlobalKey<ScaffoldState>();

class StudentList extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        drawer: new Navigation(),
        key: _scaffoldState,
        appBar: new AppBar(
          title: new Text('Student List'),
        ),
        body: new ListView(
          children: _constructList(),
        )
    );
  }
}

parent_profile.dart code

final GlobalKey<ScaffoldState> _scaffoldState = new GlobalKey<ScaffoldState>();
class ParentProfile extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      drawer: new Navigation(),
      key: _scaffoldState,
      appBar: new AppBar(
        title: new Text('Parent Profile'),
      ),
    );
  }
}

nav_drawer.dart code

import 'package:flutter/material.dart';
class Navigation extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new Drawer(
      child: new ListView(
        children: <Widget>[
          new DrawerHeader(decoration: new BoxDecoration(color: Colors.indigo),
            child: new Container(alignment: new Alignment(0.0, 1.0),
              child: new Text('Pupil Watch',textAlign: TextAlign.center,
                style: new TextStyle(fontSize: 28.0, color: Colors.white),
              ),
            ),
          ),
          new ListTile(
              onTap: () {Navigator.of(context).popAndPushNamed('parentProfile');},
              title: new Text("Parent's Profile", style: new TextStyle(fontSize: 18.0),)),
        ],
      ),
    );
  }
}

On opening the app it opens with a listview with a navigation drawer.
Open the navigation view and open parent profile
This opens the Parent profile activity with a navigation drawer
Again open the drawer and click the parent profile
This causes the issue and opens the parent profile again but when we click back button results in a black screen
Need to click back button again to go to the student list activity

Sorry for the late response.
Is this still an issue in recent Flutter versions?

rashedmyt · 2018-07-16T15:22:18Z

haven't tried since then.. will let you know

Feel free to create another issue if you think there is something that needs to be done.
