I can't figure out flutter. I see so many rave reviews. But I personally tried it and strongly disliked it. The toolkit and Android Studio run horribly slow - like really slow. And the output is basically this generation's flash. Some of the samples I tried on their gallery are mediocre. Very slight, but noticeable sluggishness. Some are just terrible; the 2d transformations moves at like 7fps. Plus there are so many…

Issues with/dislike of Dart is a pretty common refrain. This project is still very early days but the intent is to bring Flutter into Typescript https://github.com/chgibb/hydro-sdk Eventually I hope to bring Flutter to C#, Haxe, and (maybe stretching it) eventually Kotlin, Java and Scala.

Honestly I don't get the appeal of Dart/Flutter for this use case for two major reasons: 1. Dart is garbage-collected; and 2. Dart has optional typing, which is to say it supports type hints but is essentially dynamically rather than statically typed. This presentation claims low overhead so I'm open to be proven wrong here. I wonder how much of that (if true) is Flutter and how much is Wayland (over X). I'd really l…

An important distinction is Embedded and Real-time. Embedded is the all-encompassing tent, while Real-time is a subset thereof. Embedded includes things with GUIs, like fridges. We're not dealing with 128k of RAM. These can run basic GC'd apps just fine. Pauses really aren't any more of a concern than on desktop, or even less so.
