Flushbar without context

[sm2017]

How can I show flushbar without context?

You can't. Flushbar needs a context to push itself into the route stack

In first route, when we navigate to second route, we have a background task, the task may fail, I want to show a message to end user by flush bar, UI is in SecondRoute (or may be another route) and In FirstRoute after (or before , no matter) navigation, background task runned and after a while may be failed

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(
    title: 'Navigation Basics',
    home: FirstRoute(),
  ));
}

class FirstRoute extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('First Route'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Open route'),
          onPressed: () async {
            await Navigator.pushReplacement(
              context,
              MaterialPageRoute(builder: (context) => SecondRoute()),
            );
            Flushbar(
              title: "Hey Ninja",
              message:
                  "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
              duration: Duration(seconds: 3),
            )..show(context);
          },
        ),
      ),
    );
  }
}

class SecondRoute extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Second Route"),
      ),
      body: Center(
        child: Text(
            "I want to show here Flushbar, Flushbar.show called in FirstRoute"),
      ),
    );
  }
}

If we don't use context it will be much more convenient.
Like this library https://pub.dev/packages/get or https://github.com/MMMzq/bot_toast, context is not needed.
