Well, I did work on a Flutter app with a tiny team between 2018-2021 and we had 15M installs, were app of the day, got featured multiple times in the App Store, got Google’s design award, were a preloaded app on iPhones in Apple Stores in several countries, and were overall doing quite well.

It was a very focused app though, so the size of our codebase didn’t really grow with the number of installs.
