Please pin point the relevant DX issues so that it can get recognition and get fixed

I feel like I'm having a deja-vu. I remember having a similar discussion in the past and it turns out it happened exactly one year ago when Flutter 2 was released: https://news.ycombinator.com/context?id=26336657 Every framework has bugs and feature requests that are fighting for resources. And the ones affecting you _always_ seem more important than the ones that don't. That being said, the fact that memory leaks in…

> While that's great, I was hoping it would be like in Rust, where each enum variant can declare its own state components, but unfortunately it seems to be more like Java: same state for all variants. Yes, the enhanced enums we shipped in 2.17 are like Java enums. We are also working on support for pattern matching and algebraic datatype-style programming: https://github.com/dart-lang/language/blob/master/working/05.…

Any thoughts on the freezed package [0]? That's what I use currently for ADTs and exhaustive pattern matching on them, would be cool to see similar syntax in the official implementation. [0] https://pub.dev/packages/freezed

> The web is the cross platform that runs everywhere (as in in a browser or webview) Yes, but the web is crappy system for designing UIs in. As a community we've got good at designing UIs with web technologies (HTML+CSS), because we have no other choice if you want to build web-apps. But the level of experience we've gained with those tools has hidden the fact that they have some real issues - mostly due to the fact…

Interesting, I've had the opposite experience. I'd love to develop in native with something like Flutter or React Native, but I find CSS to be much easier and more flexible to use. The base components always /seem/ flexible enough until I want to do something visually complicated like add an animation that blurs an image on hover. I know CSS is horrendous in consistency, but it's piecemeal development has led to it h…

We just built a desktop app with QML in a CMake-based Qt project, and I've been pleasantly surprised by the experience. Our brief experimentation with Qt Widgets, on the other hand, revealed a shocking level of dysfunction in basic UI-layout implementation, in what is supposed to be a very mature UI toolkit. But it seems that they're basically abandoning Widgets at this point, so ¯\_(ツ)_/¯.

So interesting, even after years of doing QML, layouting with widgets makes for me much simpler to get what I want

I think this might be a bit of an outlier honestly. Reading the bug report my takeaways were the following: 1. Here is a specific issue we ran into which to be fair is unacceptable in terms of perf but a blinking cursor in an otherwise idle application has crazy high CPU usage numbers trying to run the animations associated with the blinking cursor. 2. They tried the same thing on Linux and CPU usage was 0% so alread…

I don't know if there is a larger issue because this show stopping "outlier" has stopped me from exploring Flutter any further. I'll give it another try now that a new major version has been released. The question in my mind is whether Flutter is consistently and significantly more resource efficient than web technologies for my particular use cases.
