Except they do. Google Pay / Wallet is built in Flutter, and so was Stadia. It's a bit nonsensical to think that they'd rewrite every existing app they have in Flutter, even if it is their own toolkit. Google doesn't believe Flutter is the be all, end all in app development. But it is certainly the best cross platform app toolkit out there. But guess what, Gmail and their other apps don't use a cross platform framework, so the statements "Swift UI makes it easier to brand your iOS app" and "Flutter is a great cross platform app framework" aren't mutually exclusive, hell Flutter can even use SwiftUI views as part of it's Widget hierarchy via PlatformViews.
This post comes across as yet another person that's never actually investigated a tool casting aspersions on it because of what they hear online.
Your examples are honestly pretty weak: a formy app that's main criteria be that it works and doesn't send money to the wrong person (which you could pick almost any stack to do), and a platform that doesn't exist anymore.

Well Stadia is dead and Google Pay and Wallet are toy apps. I didn’t just make the citation up. Google themselves said they want to move toward Apple’s native UIKit
From the cited article
> Google concluded that it was time for the latter route, and that Apple’s UIKit had matured enough for internal needs
That’s not exactly the rousing endorsement that you think it is. The whole problem with Google is that they have no focus, vision or direction compared to the other BigTech companies.
And that goes back to the point I made in the first place. We know that Apple isn’t going to abandon Swift while they are moving away from Objective C because the entire company is behind it.
Microsoft isn’t going to abandon C#. And you knew when they moved to .Net core they were committed to it
