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?

reWalls : Wallpapers From reddit
This is something I've been working on for quite a while. It's a wallpaper app that lets you browse your favorite subreddits and allows you to set the image as wallpaper or download the image. It's still in it's early stage, so your feedback is highly appreciated.
You can try out the app here: https://play.google.com/store/apps/details?id=com.bimsina.re_walls
Also the project is open source so you can contribute to the project here: https://github.com/bimsina/reWalls

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.

Sometimes My dio locks itself and sometime it works idk why?
Actually I am using dio package for intercepting every request made from my end, and before accessing the options or header specailly token in my case , I am checking for token if it is present or not, If token is found then I proceed and if not then getTokenMethod() is called and dio is locked before doing so, after the token is found using then function and when complete, I unlock my dio, but this doesn't seem to be the correct way I think so, because in these conditions my dio sometimes stuck and keep loading the request like if it is in lock mode.
To get rid of this continuously loading of dio request I tried to use timeout with the dio reqeust but that also dosen't seem to work, my dio is working perfectly with headers sometime, and sometime its not working

Releasing today: A water chemistry simulation app using dart:ffi, isolates, charts_flutter, flutter_bloc, and provider!
I'm excited to release today an app for simulating the chemistry of chlorine and ammonia in water, a topic of particular importance to wastewater engineers and operators. The interactions between the two species are fairly complex and boil down to a series of differential equations which need to be solved. I was inspired to create this when I saw a tool the EPA had created for doing the same thing — I loved seeing the visualization of these reactions and wanted to recreate it in Flutter.Since there are no dart packages for solving systems of differential equations, I used the very popular C++ library boost for simulating the reactions and connected to the generated library using the dart:ffi package. To keep the main thread unburdened by the heavy C++ code, I used isolates to offload all the simulation work.State management is accomplished using the flutter_bloc and provider packages. And charts of results are presented using charts_flutter.Hope you enjoy!Github: https://github.com/dnys1/breakpointApp Store: https://apps.apple.com/us/app/breakpoint-simulator/id1491638603?mt=8Google Play: https://play.google.com/store/apps/details?id=com.humbleme.breakpoint

Why UI lags in the Flutter gallery app? Really Unexpected
I looked at Flutter Gallery app today and unexpectedly UI really lagged (compared to native). Especially switching between tabs.I have been rewriting our app from native android to Flutter for about 1 month now and my UI always does not feel like Android. What I mean by "feel" is things like tab, chips clicks or scrolling in GridView with images and loading bars. I have previously used ReactNative and even though it had some minor issues, at least the feel was equal to native development.I don't know if it is just me, but I have tested on my own daily phones: iPhone X and Xioami miA2. I have not tested on any emulators, but all native apps feel native in those phones, expect Flutter ones... I am looking for some hints or perhaps I am true, that Flutter does not feel native at all.

Best solution for storing data?
I'm making an app based around foods/ingredients and i find myself with 2 options:A. Use Firebase non-relational storageB. Use flutter for the front-end but for the back-end use Aquaduct framework made for dart to establish a connection with postgreSQL.Which do you would be the best alternative considering speed? Or what could be your reasons to choose one over the other?
