Could you build this?

Partial While standard Flutter apps are easily vibe-coded, developing a performant procedural rendering engine without static image assets alongside 2D physics/gravity dynamics requires deep mathematics and game dev expertise.

What it would actually take: A real version requires implementing a 2D rigid-body physics simulation (such as Forge2D or custom Verlet integration) in Flutter CustomPainter. The procedural engine demands custom shader (GLSL/SPIR-V) programming and algorithmic canvas rendering for celestial bodies and constellations, coupled with strict 60fps frame budgeting. Deep knowledge of game physics, mathematical geometry, and low-level Flutter graphics pipelines is essential.
