Dart/Flutter now has macros/metaprogramming

The dart ecosystem is way richer than I expected it to be. So far I've found good options for everything I need and in more than a few cases the libraries are better designed than the JS equivalents.

I can't speak to Linux desktop performance but on the Mac my Flutter app sips CPU and memory.

Google abandoning it is a real risk. If they continue to support it I think Flutter has a great future.

So I tried the exact same test on a last gen Intel Macbook Pro. Same thing. 20 to 40% app CPU usage not including WindowServer. Putting cursorOpacityAnimates: false "fixes" it, seemingly similar to this:

This is more of an eyebrow raising signal to me. This is not quality congruent with a multibillion dollar company backing. If the cupertino widgets are in this sorry of a state they probably should be marked as such.

But perhaps someone more invested in the ecosystem may want to submit that pull request. It seems like low hanging fruit.

Sounds like this is specific to the Cupertino widgets? I’m not using those because I think they’re just going to put you in the uncanny valley of almost native Mac UI.

The material stuff looks good and performs well and at this point users have more desktop apps on their machine that don’t use native controls than do.

My flutter app is way more responsive and efficient than the electron prototype it replaced.
