I tried Flutter in 2020 for a side project but decided not to use it. It felt clunky and slow. I later ditched the side project also since I decided to not build any mobile Apps for now. Maybe I'll revisit Flutter if I ever consider building a mobile front end for any side-projects.

For what it’s worth Dart is hands down the nicest OOP language I’ve ever used in my opinion. It’s like they took all the good things about JS and Java and cut out all the bad parts. What’s left is basically Dart.

> nicest OOP

That's the thing. Dart is useless for my preferred style of programming. A modern language without ADTs and pattern matching is not even meeting my bare minimum for acceptable to use. Not just this, but the docs explicitly said the don't want these basic features.

People are talking about a better developer experience, but hardly anyone is talking about the user experience with apps built with this tech. I don't feel it's great, especially on older devices. Take google pay, a showcase flutter app. It's a laggy mess on an iPhone SE 2016, whereas the "old" google pay ran perfectly fine. On top of that, many google apps I use these days will just freeze and stop accepting touch i…

I'd just like to chip in with my (opposite) experience:

I semi-recently developed an app using Flutter and used an iPhone 6, a 6s, and my old Redmi Note 5 as a baseline for performance testing. While I'll admit I wasn't doing anything particularly graphics heavy (at most: sliding modals and some animations), I wasn't able to get things to dip under 60fps on either platform.

As for the GPay app, the only performance issue I could notice from testing just now was a dropped frame while quickly scrolling through the "explore" page. Otherwise it works perfectly on my Z Flip 3.

On the other hand - have you considered upgrading devices? I always hate whipping out the iPhone 6s (same A9 CPU as your SE) because it runs like hot garbage in most cases... a recurring theme in the iOS space.

> Apart from Qt, but the licensing issue is a hindrance Qt is LGPLv3, which is really a problem only if you plan to develop embedded software. Sure, there are a few GPL v3 modules here and there, but it's mostly very specific stuff (virtual keyboards, Wayland compositors, ...)

How is it not a problem if you want to sell closed-source software? I guess you can dynamically link desktop applications (although I'm not sure how this works in Apple's Mac app store), but you can't do that with mobile apps.

You can use LGPL with closed source so long as you provide object files to relink against.

There's definitely competitors opening up and realizing the space is worth the investment. C# Maui for example, especially with Blazor, is extremely cross platform as well(including web), but it has full party support in C#.

To be fair: Dart is relatively straight forward and simple to learn. You should have decently qualified developers be productive within a week. But forcing a new language on people usually doesn't go well.

Sure, I'm not trashing the language, because I know nothing about it. Our whole dev team is C/C++, with random people who know Python and a few other things. I'm the only one who knows Swift. They're bright people and not hostile toward new ideas, but they're already overtaxed and can't cater to an outlier project written in a language no one knows and built on a framework no one knows.

Can Flutter/Dart dynamically load code yet for apps that need plugins? Love the concept but eyeing it for b2b style apps that need extensibility.

Depends on what you mean exactly. But you can split dynamically load code (all uploaded at once to the Play Store) via https://docs.flutter.dev/perf/deferred-components

What about .NET with MAUI / Xamarin?
