> My only gripe is that there is no 3D game engine for Flutter, again Dart is great, lots of solid packages like GetX just make the overall development progress as advertised.

Yeah they're going to work on 3D afterwards (potentially, the main dev for 3D left the Flutter team and is back on Android if I recall correctly), it's not a huge priority right now. Also, it's not recommended to use GetX, there are some issues with it, a major one being it's like a framework within a framework, and it essentially rewrites a lot of Flutter. Better to use Riverpod, Bloc, Signals, ReArch or something else.

For 3D however, I've been looking at Dioxus which is in Rust, they're making a native renderer the same as Flutter (ie not webviews) called Blitz, and they're making good progress on the mobile side. This renderer can embed Bevy, a game engine also written in Rust, and Bevy can also embed Dioxus native, which I thought was really cool, it's bidirectional embedding.

I didn't know Expo explicitly made you pay, I thought it was only optional. Now that I look at it, seems like it's for high priority builds but still, can't we just build on our own servers? If not then that's a big con, I don't want to rely on an external service just to build my app.

What are you making in Flutter?
