```dart

import 'dart:async';

import 'package:did_change_dependencies/did_change_dependencies.dart';

import 'package:flutter/material.dart';

import 'package:rxdart_ext/rxdart_ext.dart';

class Bloc {

  Stream message$ = Stream.empty(); // just demo

}

class MyPage extends StatefulWidget {

  const MyPage({Key? key}) : super(key: key);

  @override

  _MyPageState createState() => _MyPageState();

}

class _MyPageState extends State with DidChangeDependenciesStream {

  final bloc = Bloc();

  final subscriptions = >[];

  @override

  void initState() {

    super.initState();

    final handle = (String msg) {

      // safe to access ScaffoldMessengerState.

      ScaffoldMessenger.of(context).showSnackBar(

        SnackBar(content: Text(msg)),

      );

    };

    subscriptions <<

        didChangeDependencies$

            .exhaustMap((value) => bloc.message$)

            .listen(handle);

    subscriptions <<

        didChangeDependencies$.listen((event) {

          // do something when `didChangeDependencies` is called for the first time.

        });

  }

  @override

  void dispose() {

    super.dispose();

    subscriptions.forEach((s) => s.cancel());

  }

  @override

  Widget build(BuildContext context) {

    return Container();
