Get Current Context for Overlay Flutter - flutter

Question

I want to display notifications that are being processed by a provider on an open gRPC stream. This is handled by notificationProvider.dart:
if (notification.type == 0) {
showOverlayNotification(notification);
} else {
notificationList.add(notification);
notifyListeners();
}
showOverlayNotification() then displays custom notification Widget OverlayNotification() on top of the current screen that user is in, like:
showOverlayNotification() async {
OverlayState? overlayState = Overlay.of(**context**);
OverlayEntry overlayEntry = OverlayEntry(builder: (context) {
return Positioned.fill(child: OverlayNotification());
});
overlayState?.insert(overlayEntry);
}
Now the problem is that I don't know how to get to the current context the user is in?
Android was pretty straightforward with this, but I can't seem to find this in Flutter..
How do I display overlay widget to a current context?
Do I have to keep track of it in a global variable in the end?
Can I find it through NamedRoutes?

Answer 1

can do something like this, fyi if you don't want to use navigator to pop current view you can create a navigator key as shown here
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
_buildPopupMessage(BuildContext context){
return Center(
child: IconButton(
onPressed: () {
showDialog(
context: context,
builder: (context) {
return FittedBox(
fit: BoxFit.scaleDown,
child: AlertDialog(
title: Text(
'title text',
textAlign: TextAlign.center,
),
content: Text('message text here',
textAlign: TextAlign.center),
actions: <Widget>[
TextButton(
onPressed: () {
debugPrint('closed pressed');
Navigator.pop(context);
},
child: Text('close'),
)
],
),
);
},
);
},
icon: Icon(
Icons.live_help,
),
),
);
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body:_buildPopupMessage(context),
);
}
}
