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I certainly don't think having my app sticking out like a sore thumb, using a design language from old outdated iOS versions is "a good thing"

The new direction isn’t Liquid Glass, but a more unified branding across Android and iOS. WhatsApp, Google Maps, Instagram, Netflix, Prime Video, and many others don’t look dated, because they don’t make heavy use of the older iOS design language at all.

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.

That’s not a good thing if you don’t adapt liquid glass. I’m an iOS developer.
