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.

[Breaking Change Proposal] Make CupertinoThemeData.brightness nullable
Hi all, I'd like to make CupertinoThemeData.brightness nullable. Currently it returns Brightness.light even when set to null. This is going to be a breaking change because it breaks an existing widget test. You can find the design doc for this breaking change here: https://ift.tt/1eWmIPy

Invoke print dialog from flutter_web project?
I'm developing an application that generates some one-time use codes that need to be printed out. If this were an Angular application, I could just include a window.print() link on an element in the template. Is there some equivalent way to invoke the browser's print dialog from a flutter_web

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?

Is it me or do Flutter apps have a specific "look"?
I feel like I can look at an app and say, "Ok, this app was done in Flutter". I know by convention we use material design, but the do the same in Android, right? What is it? It's the look of the widgets and the way the animations look.
