Oh this totally reminds me of the BLoC pattern[0][1] that everyone kind of... really gritted their teeth through. It just wasn't at all an appealing way to structure data flow and I was kind of surprised that it was the architectural choice that was being pushed.

90% of the time, it felt like simple IoC plus an app-wide singletons would have been enough for most apps-- trying to get everyone to aadopt BLoC was painful and kinda meh. It's probably just that I never developed a sufficiently big app at scale with lots of devs to see why BLoC was the best way.

That said, I'm also reminded of the Boring Flutter Development Show[2], quite possibly the best produced resource I've ever seen as an intro and ongoing guide to a piece of tech. It is excellent.
