Need some advice on a school project we are struggling with- a flutter mobile app to replace access badges.
We have about a month to develop a rudimentary system that should demonstrate a replacement for employee/customer access badges. (For example, gym members usually use magnetic chip cards to gain access to the premises. We want to replace that with an app.)The system is basically:Arduino (representing the "gate" with a green/red bulb )<<Server>>Flutter app(handles user ID)So the gym member opens up the app, sign in to their account, Id with fingerprints, then they can scan a barcode that's tied to a gate. The server receives their request and answers with granted/denied which is sent to the Arduino as a binary signal (and a Green/red light is lit).What we are having trouble with is working with a backend that could communicate with both the flutter app and the Arduino, and also pass signals between them. We've tried to connect Arduino to AWS IoT and it kinda works, but we're not sure how to communicate with it through amplify_flutter. Is this something that would be more suited to Firebase?Also, any general advice would be greatly appreciated, as we are getting really nervous about how little we've achieved so far and how little time we have left to work on it.

How do companies rank listings on their site and what's an effecient way of doing it in flutter.
I have an app idea that I would like to develop on flutter, though my question isn't flutter related I thought it'll be interesting to understand from flutter point of view too. I am just in the early stages of gathering information at the moment.In one part of the app, people can advertise themselves/jobs to be seen by potential customers. I will be providing the standard filters such as distance, reviews, price, etc. But I am not too sure what metrics are used and wondering if anyone can shed some insight or point somewhere.Thanks.

Flutter vs Xamarin/React Native
Hi flutter enthusiasts. I want to develop a small cross platform app. I don't have high performance requirements for my project, but I want the UI to feel snappy and modern. I wanted advice in general about which cross-platform framework is better for my requirements, and for Flutter what are the biggest criticisms that you have with the framework.

What do you all think about future of flutter/dart. Not the Future in flutter/dart
For years I was into web development and one reason I hated in app development is that you have to refresh it to see the changes and they aren't so fast. But now this AOT/JIT compilation capacity have made flutter super cool and I feel it as good as web dev + performance added. I feel dart as a evolved, carefully designed language and it can be a major language at some point. What you all think?

Introducing a Flutter Charting Library: Graphic
About a year ago, we published a Flutter charting library: Graphic, aiming to help Flutter app developers in data visualization. It evolves a lot in the past year and has these features now:A Grammar of Graphics: Graphic derives from Leland Wilkinson's book The Grammar of Graphics, and tries to balance between theoretical beauty and practicability. It inherits most concepts, like the graphic algebra.Declarative and Reactive: As is encouraged in Flutter, the chart widget of Graphic is declarative and reactive. The grammar of data visualization is implemented by a declarative specification and the chart will reevaluate automatically on widget update.Interactive: With the signal and selection mechanism, the chart is highly interactive. It is easy to pop a tooltip or scale the coordinate.Customizable: With the shape and figure classes, it's easy to custom your own element, tooltip, annotation, etc.Dataflow Graph and Operators: Graphic has a internal structure of a dataflow graph and operators. That is how the reactive reevaluation and interaction is implemented.Here is the documentation and Example App, and a introducing artical.If you need charts in your Flutter app, welcome to have a look and try!

Did you know that extensions on generic types are possible?
Dart doesn't have a Self type to express the fact that a method returns the same type as its receiver or expects that type as one of its parameters. But there's a workaround. Did you know that you can make the target of an extension generic?Here is an example:

extension<C extends ChangeNotifier> on C { AspectNotifier<A, C> aspect<A>(A Function(C) aspect) { return AspectNotifier(this, aspect); } } 

You can now use notifier.aspect with any ChangeNotifier and the parameter type of the the function parameter is always the correct type. I don't think that you can achieve the same thing just with a method.Here's another handy extension that makes dealing with nullable types monal-like:

extension <T extends Object> on T? { U? map<U>(U Function(T) transform) { final that = this; return that != null ? transform(that) : null; } } 

Assuming that s is a String? instead of s != null ? int.parse(s) : null you can now use s.map(int.parse) which – if you're used to such style from other languages like Swift - looks nicer. If you'd need to also pass a radix, the advantage melts away, though: s.map((i) => int.parse(i, radix: 16)).Still, I like the expressiveness of extensions.
