Is that actually true though? Most major Google apps predate Flutter. I was under the impression that a lot of their apps are either custom web view wrappers or native with shared C++ code for business logic. Stadia and Google Pay are the only consumer facing Google apps I’m aware of that are made with Flutter.
Ads is all flutter on mobile and Dart on the web. Fuchsia is an OS that is also using Flutter for their entire UI layer. I think there’s more a case of there isn’t an argument for doing but rewrites just because Flutter is now a thing but in a greenfield scenario it would be a serious contender
But that’s not demonstrating the promise of a great cross platform experience.
