https://flutter.dev/showcase has a few examples. Flutter is everywhere at this point. TikTok in China (Douyin), PUBG Mobile, MGM Resorts, eBay Motors, Kijiji.com, Grab are a few off the top of my head. And of course a whole bunch of Google apps (GPay, Earth, Classroom, etc.), Toyota cars, LG TVs, Google's own hardware devices, etc. Tonal is probably the app I used most often that's Flutter. Caribou Coffee, Betterment, Norwegian Cruise Lines, NuBank, Realtor.com are other random apps I've used that are Flutter.

small nit: many daily driver apps in China are partially Flutter. But TikTok is not at the present
small nit: douyin is. is it possible you read "TikTok in China (Douyin)" as "TikTok in America"?
Do you have a source for that claim? I'm pretty sure that is incorrect. Bytedance has said they use Flutter but for other projects.[0] Douyin is not mentioned anywhere.

I don't have access to any devices with Douyin on it, so I cannot confirm current usage.

My knowledge of their usage is from discussions with ByteDance some many years ago when I was in charge of the Flutter project at Google. At the time they were using Flutter in 50+ applications (probably most of them internal), including Douyin (TikTok for China) as well as physical hardware kiosks on their campus, web apps, etc.

I just tested Douyin 23.5 from 2022[0] and it does not have the two finger scroll bug.[1] It is of course possible they were carrying their own patch for it all this time but that seems unlikely. I doubt they are using Flutter or if they did it must have been a long time ago.

[1] https://github.com/flutter/flutter/issues/11884 - click on the search button in Douyin on the main page and search for something to get to a regular ScrollView. You don't need an account for this.

Flutter two finger scroll "bug" is gone.

I wouldn't say its unlikely they carried a patch for it, I just wrote a framework patch that I apply at build time in CI and locally.

I refuse to sideload arbitrary APKs, especially from bytedance. I feel bad because that is irrational, you did, and it'd be really helpful if I did and just did this myself, but, you should install FlutterShark and check: https://play.google.com/store/apps/details?id=com.fluttersha...
