This is a welcome addition but why should Flutter devs use this ?

Seems like it requires 32gb of ram! Also Flutter is already very mature and can produce not only near-native mobile apps (the difference is almost negligible) but can target desktop and even web applications.

I do wonder how much of a boost skip offers vs Flutter's mobile apps. Will give skip a try when dram prices normalize.

See my response below on the KMP question: the comparison with CMP mostly applies to Flutter as well.

> near-native mobile apps (the difference is almost negligible)

Not as of the advent of Liquid Glass on iOS (and, to a lesser extent, Material Expressive on Android). Flutter isn't going to be implementing these new interface conventions[1], and so the UI for these apps are stuck on the last generation and are already starting to feel outdated.

Flutter's grim outlook has resulted in a surge of interest in Skip, and it was one of the drivers for us to open up the platform and catch the wave. If you love Dart, or if your apps don't need to look native (e.g., games or very bespoke interfaces), then Flutter might continue to be acceptable. But everyone else is starting to look elsewhere, especially in cases where their business depends on their apps feeling premium and native.

  • > Flutter isn't going to be implementing these new interface conventions

    To be fair reading those updates it sounds a lot more positive than this comment makes it seem. I.e. "they're pausing design updates while they figure out the best way to do it" rather than "they're not going to bother":

    > This strategic pause on design updates gives us the space to ensure the long-term health and maintainability of Flutter's design libraries. We are committed to being transparent with our contributor community as we explore these options and will have more to share on our findings and future direction in the coming weeks.

    and

    > The material and cupertino libraries are being decoupled into standalone packages to accelerate feature development. All new work for iOS26 updates in Cupertino will happen in the new packages once established in flutter/packages.

  • Flutter is undergoing a major refactor where they're decoupling Material and Cupertino into separate packages. This is the reason why they're not implementing those new conventions right away. The way you've framed it is pretty disingenuous.

    • It really isn't. Did you see their latest time estimate (https://youtu.be/W4olXg91iX8?t=538)? Late 2026 just to get the widget sets broken out into separate packages? And only then can they start considering modernizing them and trying to mimic the latest UI?

      Flutter can't even get animations to look and feel right for iOS 18 and below (read through this thread and every other HN/Reddit thread that mentions Flutter vs. native components). Do you really think they'll ever get Liquid Glass looking and feeling convincing, let alone performing acceptably?

      Read over the 100+ comments in the GH issue I posted. You see actual Flutter contributors — not people who merely vibe-coded a Potemkin L.G. demo and declared victory — saying that it is effectively impossible.

  • Well sorry. But Android UI is bad just bad. The settings, the menus. Its bloated and almost as if they deliberately made it annoying to use. It just sucks.

    • Have you seen iOS or macOS settings, like ever? Especially on macOS, the UI is infantile, you have settings in different menus that change each other (mouse / touchpad scroll direction, two buttons in two menus, they change each other). On iOS you have amazing features like a wheel spinning forever without telling you there is a problem and what it is (like, for an app with in-app purchases, you must have a payment configured, otherwise the app installation just spins forever).

      Compared to that, my (OxygenOS version of) Android UI is pretty good, concise, flexible and customisable if I want to. I hate the ambiguity of gestures, so I keep the buttons for navigation. I don't want everything splattered on the home screen, so I use a different launcher than the default. The menus are all logical.

Dunno about Skip, but I can always tell when an app is Flutter. They feel like crap. Everything's a bit off with the native looking widgets. And fully custom designs still animate a bit weirdly. And they definitely still stutter. Somehow a tier below React Native.

  • Flutter re-generates the entire layout every tick and diffs it (immediate-mode), like a game engine. If your device isn't quite fast enough it'll lag, yep. RN is retained mode (but written in immediate-mode style and the diffing only happens when it has to).

  • I've noticed several of the apps that don't respect device animation settings were built with Flutter. Not sure if that's a limitation of it or if the developers culturally don't bother.

Flutter is fine if you don't care about performance, accessibility, have no need to access native capabilities or non-fluttered widgets (ex: the Google map integration is awful) and overall just want to make an internal app.

The cost of making an excellent flutter app is about the same you'd pay making fully native apps. Except that you're always paying for Skia's costs with Flutter.

This recommends 32GB to run _everything_, so xcode, gradle, emulators, simulators, etc. Not fully surprising.

Flutter still doesn't support liquid glass on iOS so it doesn't seem like a serious contender to me at this point. And due to the nature of how Flutter is implemented, it's going to continuously be an uphill battle. Maybe it's fine if you intend on having a completely custom UI and don't care about platform look and feel.

  • > Flutter still doesn't support liquid glass on iOS

    Literally every iOS developer under the sun will tell me that this is a good thing.

    • Why? I'm an iOS developer and, while I don't love everything about liquid glass, that is the current design language of iOS.

      I certainly don't think having my app sticking out like a sore thumb, using a design language from old outdated iOS versions is "a good thing"

    • No. I’m an iOS developer and will not tell you that, except to say it’s a good thing to have one more reason for the people not to use flutter.

  • In general, the "render UI as if it were a video game" route feels like a bit of a dead end on mobile to me. On desktop it's more workable but still isn't without issues.

  • I've heard bad things about liquid glass and plan to skip that OS release, so not implementing it seems like an advantage from my perspective.

Tried using Flutter a year ago to make a simple Mac app. I don't think it was ready at the time. Also poor documentation.
