Are there any UI design/theming tutorials which write clean and reusable code?
All of the Flutter UI design videos seem to follow "bad" coding practices (everything in one to three files, no use of components, no use of ThemeData for styles). Are there any tutorials that teach you how to make a good UI along with good coding practices?

is there a template builder for flutter?
Im a web dev that mostly do backend development at work (75% backend + 25% frontend). I dont learn any SPA framework as my job doesnt require me to do so. Most of the time I only used bootstrapshuffle.com (bought it last year as I thought it would save me lot of time in the long run, and it did). My question is, if I want to jump to use flutter for mobile development is there any service that provides bunch of templating like bootstrapshuffle.com that would save me lot of time with starting from scratch for the design?

First time doing a freelance project. Help me out people, please and thanks.
So basically I am about to take on my first free-lance project and would like to know how much to charge. First I am throwing together a prototype with no functionality to show the client how it will look. I asked for any design docs he may have. So how much should I be charging for the prototype? What software should I use to create the prototype? I have heard good things about Figma.​How much should I charge for the rest of the project, provided he likes the prototype. I know that with out project information it would be hard to answer so here is what I can tell you. I am implementing a mobile app that decodes messages in audio and communicates with a mongoDB hosted on an EC2 instance on AWS. Sorry if the questions are poorly worded.

What styled should go in ThemeData, and what should go in your component.dart file?
(This question is a little long, sorry about that)Firstly, I'd just like to say that I am coming from a web development background, where I would make classes (like .button which contains all the styles for a particular component/element: text styles, borders, radius, padding, and margins).Does this NOT apply to flutter? In most apps I see, it seems like all the app's colors (primary, secondary colors ...) and text styles (titles, headings, ...) are defined in ThemeData(), while other properties such as padding, corner radius, ... go in the separate component.dart file. Is this way correct? Because as a web developer I thought ALL your styles/themes should go in the ThemeData.Here's an example of a 'real-world app's ThemeData: https://github.com/flutter/flutter/blob/master/examples/flutter_gallery/lib/gallery/themes.dart (Flutter Gallery by Google).In the ThemeData, you only see text themes and colors defined. Is this the correct way to go about theming? It seems like all other files should either be defined in component files. The reason I thought this was incorrect was because it seems like you are "hard-coding" the values. In fact, I made an app this way, and I put my "hard-coded" values in another file, although I'm not sure if that was the right thing to do.Also, are library-solutions for styling popular? I found this package: https://pub.dev/packages/styled_widget, and it makes styling similar to Swift UI and Inline CSS. Does anyone use this?In summary, is there a list of styles/themes I should put in ThemeData vs the component.dart file? I believe (based off of Google's app) that colors and text go in ThemeData while all other styles go in the component file

'Animating' components based on values
Fairly new to Flutter, I was trying to implement a Container changing its margin (via list offset) while the user scrolls a listview. Got it done but that made me realize setState() is a pretty expensive function to execute each frame. I decided to use AnimatedBuilder to get the same functionality but it seems to be geared towards pre-defined animations rather than values changing (like scrolling offset). What would be a way to tackle such a problem?

How do I run notifications when the app is closed and the phone is off?
Hi all, I’m currently working on a flutter app that involves running a function to update notifications every 10 minutes. I’m struggling how to natively get notifications or any block of code to run in the background on both iOS and Android. If this is not possible how hard is it to port my flutter code to swift for native development.

Force localeResolutionCallback upon language change
Hello,I'm confronted with an interesting problem. I am using "localeResolutionCallback" to set the locale on load and to detect when the user changes the language on the device. However i also want to be able to bypass it so the user can choose a separate language from the one his device is set to.This seems to be impossible because "localeResolutionCallback" if i read the docs properly only works on load and when a device language was changed.Does anyone know how to force it to trigger this function? I do not want to use the "locale" key of material app (which works) because i would have 2 similar operations that are conflicting and i absolutely need "localeResolutionCallback" for detection so that one wins.​Any ideas? Thanks​PS: i am indeed using a listener to rebuild materialapp but like i said it doesn't trigger "localeResolutionCallback "

Flutter is broken on Linux 5.5 and newer kernels
Just a heads up if you use Linux and Flutter appears to be broken (it gets stuck when you build an Android app, can't hot reload, test or debug an already running app) that this is a bug and the only workaround is to downgrade your Linux kernel to 5.4 or older.https://github.com/flutter/flutter/issues/49185Spent the better part of the afternoon trying to figure this one out. Most distributions are not affected yet, but rolling release ones such as Arch Linux already are, or if you run a custom kernel.
