Resolve local hostname
Hello all, I've been making a simple mqtt application for my raspberry pi running node-red and it's going pretty well.I have two mqtt brokers running locally and a remote broker. I can access the remote broker just fine but when I try to connect to the local mosquito broker running on pi through its hostname (raspberrypi.local) I'm getting error flutter os error: no address associated withhostname, errno = 7I've looked into this error and found out I may have to use something like mDns package. I'm not sure where to head next.The raspberry pi will be connected to existing WiFi and it may have different IPs every time it reconnects.

Getting input without textbox
Is there a way to get text input without actually having a text input with a listener?Basically I am using some android devices with barcode scanners. When you scan a barcode the numbers are sent through the device as typing. I need to grab that text and deal with it.My current hack:1) have text input on the page2) autofocus the text input so typing goes to it3) hide the keyboard4) capturing typing to the text input5) do a big song and dance to let the user type in the text input if they really want toI would rather skip steps 2 and 3 and 5... but to do it, I need to capture typing without an input selected

ancestorInheritedElementForWidgetOfExactType is deprecated
After v1.12.1 ancestorInheritedElementForWidgetOfExactType is deprecated. We should use getElementForInheritedWidgetOfExactType now. How do I edit this BlocProvider?

import 'package:flutter/material.dart'; Type _typeOf<T>() => T; abstract class BlocBase { void dispose(); } class BlocProvider<T extends BlocBase> extends StatefulWidget { BlocProvider({ Key key, @required this.child, @required this.bloc, }) : super(key: key); final Widget child; final T bloc; @override _BlocProviderState<T> createState() => _BlocProviderState<T>(); static T of<T extends BlocBase>(BuildContext context) { final type = _typeOf<_BlocProviderInherited<T>>(); _BlocProviderInherited<T> provider = context.ancestorInheritedElementForWidgetOfExactType(type)?.widget; return provider?.bloc; } } class _BlocProviderState<T extends BlocBase> extends State<BlocProvider<T>> { @override void dispose() { widget.bloc?.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return new _BlocProviderInherited<T>( bloc: widget.bloc, child: widget.child, ); } } class _BlocProviderInherited<T> extends InheritedWidget { _BlocProviderInherited({ Key key, @required Widget child, @required this.bloc, }) : super(key: key, child: child); final T bloc; @override bool updateShouldNotify(_BlocProviderInherited oldWidget) => false; }

Are there an alternative to DynamicData in Flutter?
DynamicData is a Reactive collections based on Rx.NetDynamicData is really helpful when you need list filtering, grouping, etc without changing the source list. The closest I found in Flutter is MobX ObservableList.If you guys know the alternatives in Flutter (or on the other frontend framework for that matter) that would really much appreciatedThank you

I wonder why Flutter team not starting a backend framework?
I know there is a lot of dart framework but none of them is supported by Google so they are not popular in the communityI wonder if we collect enough signatures and send it to Flutter team maybe they could consider making a backend framework for Flutter developersYou can sign here

Ending 2019 by celebrating 10k downloads of my app "Flutter Widget Guide" on the Play Store. 🎉
I was never going to start this project thinking, who would ever download it! But the response has been overwhelming. If you're deliberating about a side hustle, then just go for it. You never know what you will learn and gain in the process. I am glad to have created a community of flutter developers via this app on my Slack Channel.Happy to be giving back to the community via this app and can't wait to start brainstorming my next project. 💭Link to the app - https://play.google.com/store/apps/details?id=com.annsh.flutterwidgetguide&hl=enDo share your side projects below in the comments section. Would love to try them out :)Cheers everyone and happy holidays :)

I just made a Flappy Bird clone with Flutter and Flame, here are my thoughts
Check it out: https://youtu.be/DeoUhI-Waa0I always wanted to build games. So I thought I would give Flame a try. Here are my thoughts if anyone wants to get started with Flame as well:It was fun! After writing a few Flutter apps, I really love the language Dart. There were very little Flutter-ish codes when I wrote the game, but still it was very enjoyable with Hot Reload and other cool Dart stuff.It was quick. I had VERY LITTLE knowledge of other game engines and libraries. I always wanted to learn Godot/Unity, but never really started to. Even so, I made the clone only in a few hours. It would have taken quicker, but it was my first time and I had to figure some stuff out from the source codes, find assets etc.Flame was very easy to understand. I had only read a five part LANGAW game tutorial, and I felt like I was ready to write my own games 😝It was very performant, and the APK size wasn't big at all(5.9 MB with all the assets and audios). I know that some of the Game Engines and libraries generate big APKs.What do you think about Flame? I really enjoyed it. If anyone's interested, I'll polish the code and put it up on my GitHub.

Which state solution bigger companies are using?
Hello, I have spent about 2 months learning/coding in flutter. Coming from native IOS and Android development it was a pleasant experience. The one thing I love the most about flutter is building UI. Compared with Android or IOS it is much easier/faster (2-4 times) to build UI in Flutter.However, I feel that state management is still an issue for me. Right now I am using flutter_bloc with Provider but not sure about my choice.In native android I saw exactly the same issue regarding architecture. Google did not recommend any architecture and it became a mess in the Android world. Only 3 years ago MVVM became the suggested solution and there is still debate today.This is why I want to ask about big companies and their state management choice. Do they use redux or provider, or perhaps mobx, flutter_bloc? Can someone suggest some references for their choices? I am referring companies like Alibaba, Google (Stadia app), Tencent, reflectly app. Also if you are working in the company and use Flutter, can you share your choice? :)

Bottom navigation bar and routing
Hi there,I am developing an application where I've created bottom navigation bar with PageStorage in order to persist states between pages. But what bothers me is that I am instantiating these screens directly and I do not have routs in main.dart file.So my question is: Is it possible and good practice to add navigation to these screens since these are used only for bottom nav.bar?

A few questions about best practices for building an app's authentication
I want to build an app using flutter and was wondering if there was a better way to build an authentication system. I wanted to get things down and planned before I start working on it.​Authentication can done using google_sign_in, flutter_facebook_login, and firebase_auth.When the user is signed in or signed up, his data is stored locally using sqlite (as described here: https://pusher.com/tutorials/local-data-flutter). User data is retrieved later whenever required.When an app is opened (after the first sign in/up), while the splash screen displays, we check whether there saved user data. If no, we redirect to the authentication page, else we verify if the data matches what's on the server. If it matches, we display the home page, else, we redirect towards authentication.Does this sound alright?

Flutter Scale Aware
Hey Community!Here we go again. This one is still without a fancy README but maybe looks appealing enough to continue at a second stab? It introduces extensions to aide scale-based layouts.

Container( height: context.scale(2), width: context.scale(14.5), color: Color.red, child: Text("Hello World", style: TextStyle(fontSize: context.fontScale(16))), ) 

PS: It has a huge set of test cases and good coverage.
