That Flutter is nowhere to be seen beyond As Words, the new buggy Google Pay, and a couple of cases that Google sponsored to show something in stage during Flutter conferences.
And Flutter isn't even something that the whole company buys into, hence the counter movement from Android team and JetBrains with Compose or the whole PWA and Fungus Project from Chrome team.
Fuchsia remains to be seen if it is going to be another Android or follow Brillo's footsteps.
Flutter is used in an increasing number of production apps. I'm getting frequent recruitment offers for Flutter roles. So regardless of any skepticism you might have for the longevity of the project, saying that it's only relevant for the Ad Words people is just not true. It's being adopted, and being embraced, way outside of the googleplex.
