"Go Flutter desktop embedder". Well, that's that? Click (https://github.com/flutter/flutter/wiki/Custom-Flutter-Engin...)
"The Flutter Engine is window toolkit agnostic. " What's flutter engine? Click (https://github.com/google/flutter-desktop-embedding)
"The purpose of this project is to support building applications that use Flutter " Ok, but what's Flutter? Click (https://github.com/flutter/flutter)
"Flutter is Google’s mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time."
OOOOH. Ok.
Does that help?
It appears to produce a commercial quality cross-platform GUI, with not-so-bad looking, your only choice is Qt, be it Pyside2 or Qt/C++. For me I decide to use Pyside2.
QT is OK if your GUI is very complex and you're targeting a desktop OS.
For simple GUI QT is just too big.
For GUIs without a desktop OS (mobile, embedded), QT is not a good fit either, not enough mobile support, and their embedded license can be prohibitively expensive.
I have positive experience building moderately complex commercial quality GUIs on top of this: https://github.com/memononen/nanovg
in my case I want to build a file manager and after some research I ended up with Pyside2
I can't parse that. I know for certain that kivy runs very well on desktop platforms.
I would say for every product that is in a well defined category (like GUI toolkit) there is a default set of FAQ that an intro for it should answer. Maybe it would be a good idea to create an issue with a template of those FAQ, so other projects can use them as well.
Can I make a cross-platform GUI with it (a) in the current state, (b) maybe later? If so, what features does it support? How does it compare to Qt, Lazarus, Sciter, Elektron, etc? Does it have internal drag & drop? External drag & drop? Standard file and folder dialogs? Are widgets native or not (I suppose not, but it should be clear from a glance at the page)? Which widgets are supported? Does it have rich text support? Does it have OS-level clipboard support? Does it have transitions or not? Is it themeable? Is it fast? How large are executables built with it? Is it intended for ease of use or somewhat complicated? Do I need to write in other languages (HTML, markup, Javascript) to get things done or can everything be written directly in Go?
All of this is absolutely essential information. Nobody can reasonably decide whether to use this GUI toolkit or not without getting answers to all of the above question. So please, please explain in one sentence what Flutter is and make a section with keyword features.
[Please don't take this wrong, I'm not a naysayer. This is meant as a constructive criticism, not just of this page but of many similar ones. It sure looks like an interesting project.]
