We really should be trying to use the native GUI toolkit (or cross-platform native UI libraries like libui), not using Flutter-esque libraries that draws everything from scratch. Coherent UI is a very important point to users IMO. Users can assume that some special feature from App X will also work on App Y. For example, in macOS Cocoa, textboxes have universal readline-esque keybindings (and is configurable globally) which, as an Emacs user, very, very useful. Most Mac apps use Cocoa as the GUI toolkit, so basically all kinds of apps can benefit these keybindings. Another example of this directly benefiting users is the addition of tabs in macOS Sierra. macOS Sierra added tabs to Cocoa apps, and applications could get the feature without additional modification. I can use tabs in any application, with the same look-and-feel, in all apps. Stories like these are mostly only macOS; since Windows apps usually just re-invent all kinds of UI elements, while Linux's GUI toolkits are super-fragmented. (GTK vs Qt is one thing, and there are lots of other options!) Adding Flutter or any other UI library that draws everything from scratch is a bad idea. |
Nah, it ain't. At all! I used to believe it did. That's what we geeks think. And on mobile it doesn't matters for us either - keybings working consistently doesn't matter you're only using touch...
Same thing with React Native, everyone thought it's awesome because native UI controls. But users never care about that. For touch UIs it's more user friendly to have you app be friendly by being unique. The thing that "users prefer native" was just because users like fast and responsive UIs, if Flutter can provide fast and responsive UIs, nobody cares if it isn't native.
Even on desktop, the best UIs I've ever seen (take the new Blender's 2.8 widely appreciated UI) just use OpenGL and draw their own widgets.
People say they care about "coherence" or "consistency" when they are too clueless to figure out what's actually broken about their UIs, so they assume this is the issue. An awesome UX/I is one that would keep being awesome even if each and every button would have a different and inconsistent style, what matters is higher level. Let us stop bitching about things being incoherent or inconsistent when the actual issue is the lack of ability to figure out what is so wrong with a UI that it hinders users!
(Oh, and everyone will always want custom branding and styles, whether we like it or not... We need technology that can embrace uniqueness and incoherence and inconsistency and make it work properly and shippable in time!)
