Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Recently programming languages rust swift kotlin are all have too many tricks, make chinese developers feel uncomfortable and naive .
Also I found another project libco: https://github.com/Tencent/libco which is created by the China internet company tecent, the mother company of WeChat.

bastion - Highly-available Distributed Fault-tolerant Runtime
WeChat background service is based on C ++ coroutine architecture :libco, see https://github.com/Tencent/libco

Dart 3.1 and a retrospective on functional style programming in Dart
Current syntax is not all that bad if you are going to do OO and add various helper methods on `Message` and its subclasses, but if you just want to define your data and no behavior / helpers - then it is exceedingly verbose.
-
HTML template languages?
A future version of Dart will probably support macros which should make this all a bit easier to use, similar to how Swift 5.9 works which makes already fantastic use of its new macro capabilities by integrating mobx (or solidjs) like reactivity into SwiftUI by a harmlessly looking @Obervable annotation.

Build clean & concise UI components with Flutter similar to styled-components in React Native
Yes, that needs a bit of boilerplate for the constructor declaration and the extra build method, but I personally don't mind and with implicit constructors this will become much easier. Also, you get a performant UI as Flutter knows to not redraw widgets that didn't change.

Why is Swift so slow (timeout) in compiling this code?
I implemented a prototype version of the algorithm in that paper when exploring exhaustiveness checking for pattern matching in Dart.
I found it pretty easy to understand, but also really easy to get it to generate huge combinatorially large spaces. Some careful memoization and deduplication helped, but even so I never got the performance to a state I considered acceptable.
Instead, I went with Luc Maranget's classic approach and figured out a way to adapt it to a language with subtyping (with a ton of work from Johnni Winther to figure out all of the hard complex cases around generics):
https://github.com/dart-lang/language/blob/main/accepted/fut...
The performance (in the prototype!) was dramatically better. You can always make pattern matching go combinatorial, but I haven't seen any real-world switches get particularly slow with our approach yet, and we have some fairly large tests of matching on tuples of enums.

Dart 3: 100% null-safe, records, pattern matching and class modifiers
We are working on a proposal to add macros to the language for sophisticated compile-time metaprogramming. But the goal is more for larger-scale uses of metaprogramming—synthesizing entire new declarations—and not really about extending the syntax.
-
Confirmed. Dart 3 on May 10th
Looked at, never gonna happen (says https://github.com/dart-lang/language/issues/69). The language would have to have been designed for that from the beginning, and now there are too many constructs that would require too much "guessing" to get proper syntax right.
-
Compile-time Dependency Injection for Dart and Flutter
However, I'm super stoked to see the community pushing forward. I think when/if metaprogramming becomes available (https://github.com/dart-lang/language/issues/1482), similar magical experience would be possible in Dart everywhere. Consider following that issue and providing feedback. IIRC the champion of that feature (https://github.com/jakemac53) would like to make DI frameworks one of the key use-cases for the language feature, and will appreciate your thoughts on what primitives you'd need.

Dart 4.0 vs a new language
Dart is openly developed. If you want to know what Dart 4.0 will bring browse the Github (https://github.com/dart-lang/language).
Macros: https://github.com/dart-lang/language/issues/1482
Not sharing memory between threads was a deliberate choice and I think it saves us from a lot of bugs. Especially race conditions in multi threaded code can be a pain to debug. But more you read a long discussion here: https://github.com/dart-lang/language/issues/333
