I wrote a benchmark of game engine performance primarily geared towards the types of 2D games that are popular these days.
Here are the results for Flutter, Flame, Unity and Godot. It's a long read with many caveats, so buckle up.

Last night I thought I'd check out Flutter/Dart and after a few hours of playing around this ugly-ass prototype of an Android client for @readeck fell out. I know there's already one in the making but that's about as functional as mine so I think I might just keep working on it (unless I get bored) and maybe even finish it.
