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.

Hiring UK based Flutter developers
Will disclose company name and application link after we've had a brief chat about your experience working with Flutter and OOP more generally - knowledge of Swift will be a bonus. I have recently secured a permanent role with this company and they've asked if I know any decent UK based devs interested in a perm contract - need to be willing to travel to either Manchester or Birmingham occasionally.If you're interested, DM me a link to your portfolio of past work or anything else you feel would give a good indication of your abilities and i'll shortlist a few to have a zoom call with.If I think you're suitable I'll send you the application link and notify HR that I've referred you.

Petition to separate the flutter/plugins repository into individual projects
I find the https://github.com/flutter/plugins repository to be hard to parse these days. It contains 19 different packages and 86 PRs as I write this, which makes it really difficult to follow what is happening inside it.I'm also confused by the lack of issues tab, which causes people to submit them in the main flutter repo.Is there a reason for this? I suspect it started as a place to house a couple of small plugins and grew from there - accidental complexity as it tends to happen a lot in software development :-)In any case I'd like to propose splitting this repository into multiple smaller projects to allow for better visibility into the state of the project, as well as create new ways for developers to interact by enabling the issues and discussions tabs.

It has been 16 months since I developed Flutter DataGrid.
https://github.com/bosskmk/pluto_grid​It has been 16 months since I developed Flutter DataGrid.Currently, many functions have been added, and recently, columnGroups that can group columns to a desired depth has been added.In Flutter, there was no DataGrid, so I started making it.There is still much to be improved.Not long ago, Flutter version 2.8.0 was released.It's an honor to contribute even a little to the ever-evolving Flutter.

Severe Face Palm Moment in Progress: when you upgrade flutter and then your iOS/Xcode build needs macOs Monterrey for you to continue working on the project. Some of us just never update our macOs I guess.
